    I have a relatively new Dell XPS 8300 and I find LR4 to be as quick as LR3. The only sluggishness I've noted is the initial switch to the Develop module in a new folder. Subsequent uses of Develop in that folder are less than a second.

     

    I'd like to post more details on my computer, but I don't have access to them at the moment.

    I used LR4 Beta since it was released and found it sluggish like hell when processing G10 & 450D raw files.

     

    And after installing LR4 release version, I found the same problem. Using sliders was always in slow motion and

    it took 1-3 secs to response.

     

    After reading this forum, I tried the so-called solution by deleting cache and preview files serveral times and nothing was chagned.

     

    And finally I tried changing a profile of a photo from 2012 to 2010 and then back and forth. The strange thing is that when switching from 2012 to 2010,

    all adjustments to the photo was lost. The result was the same as a reset. Is this normal?

     

    Besides this, I also tried import raw files using Copy As DNG to see if DNG will work better.

     

    After these operations, my LR4 works as fast as LR3. I do not know what was happened. I tried to touch serveral ten photos and LR4 is still fast.

    And slider operation is almost instant. And all other operations is at lest 2-3 times faster than it was before.

     

    My computer is always the same unit: Mac Pro 3GHz, 8-core, 16G Ram, System Disk: SSD, Data Disk:Raid0 x 3, OS X 10.7.3.

     

    It seems I am dreaming but it is true. I even tried to check the screen if I am using LR3.

     

    I do not know if LR4 will slow down again....

    OK, I just installed and tried it out on my i7-quad 8GB laptop, a fairly new machine. Same result. Just as fast as 3.6, I don't notice any hicups. I wonder if I got lucky because I have new machines (no more than 1 month old)

    Thank you Andy,

     

    Tried the import Copy As DNG and the loading, sliders and adjustment brush are all quicker.  Like you said, don't know if it will last, but it's good for now.

    I have two monitors connected.  I turned off the second and the speed increase was noticable.  I hope Adobe fixes this as I like the two (Hope the new CS6 dosen't have the same issue as I REALLY use both in PS).  For now, only one monitor .  I have an NVidia card with 2 gig (rare as mose desktops are 1 gig) and the latest driver. (just checked)

    If so, I think I have to apply a LR4 patent for this! 

     

    Adobe may want to remind us there is something call DNG.

     

    Actually there is no need to edit raw files using DNG format. After of Copy As DNG, LR4 become very responsive for all my CR2 files.

     

    I also notice the CPU activity is much lower as shown by Activity Monitor.

    SPECS: Core i7 950 not overclocked, Asus Sabertooth mobo, 12 GB RAM, Radeon 5700 video with 1GB, Win7 Ultimate 64bit on SSD with programs (including LR), images on separate 2TB HDD, Dual displays.  In other words, quite capable hardware that runs anything I have ever thrown at it with aplomb.

     

    I'm going to chronicle my experiences thus far:

     

    1. Installed LR4 beta when it came out and made a test catalog of about 2000 images.

    2. Noticed sluggishness immediately, especially in develop when moving sliders.  Chalked it up to being beta and went back to LR3, waiting for LR4 final.

    3. Yesterday, excitedly installed LR4 final, which updated my LR4 beta test catalog

    4. Experienced the same sluggish performance.  Thought it was maybe because the catalog was made with the beta.

    5. Created a new LR4 catalog, and imported about 60 "fresh" raws (Nikon NEFs) to test it out.

    6. Experienced the same sluggish performance. 

     

    Sliders are slow to react to mouse dragging, and the image preview is slow to update to the adjusted values once the slider has finally moved. The slider handle doesn't follow the mouse pointer unless dragging really slowly, and it is difficult to make fine adjustments - e.g. the exposure slider sort of jumps along in 0.2-0.4EV increments.  The second display lags behind the first by as much as 4 seconds.  There is a less severe but still noticeable sluggishness to the overall navigation, such as switching between modules or scrolling and clicking in the filmstrip.  LR4 is virtually unusable in this state.  CPU activity monitor spikes on all 8 threads everytime a slider is moved.

     

    Frustrated, I started experimenting further and found some suggestions on this thread to try:

    1. Performace increases to the point of usability with the second display disabled, but this isn't a solution.  I need my dual displays!  And even with a single display, it isn't as smooth and responsive as LR 3.6

    2. PV2010 vs. PV2012 doesn't seem to matter in terms of performance.  Both are unusably slow.  But again, PV2012 is where it's at, so it needs to work!

    3. Building fresh previews doesn't seem to help, since performance was poor with the beta test catalog and with the newly created one with newly rendered previews.

    4. I imported a batch of 180 images into the LR4 catalog using "Copy as DNG" to see if that helped matters.  I have never used DNG before.  The conversion and preview rendering took about 4-5 min total for all 180 images (12mp NEFs).  Seems reasonable.

    5. Again performance seems a bit jerky but usable with only one display in use, but slows to a crawl with both enabled. The second display lags significantly behind the main display.  So DNG doesn't seem any better than just the regular NEFs for me.  And again, using DNG isn't a solution anyways, just a workaround.

     

    Soooo, I'm in a rut.  Nothing I do really seems to fix the problem.  Looks like Adobe has some investigation to do, so lets hope these posts help shed some light on the source of the problem.

    Across 4242,

     

    I have another system than yours (WIN7 64, Q6600/2,8GHZ, GTX 470, 8GB RAM) , but this is exactly my experience. You seem to have a very fast system and LR4 is still slow. I`d like to hear something from Adobe on this.

    Thanks, it seem to be a solution to get a workaround.. yes switching from profil 2012 to 2010 reset all my previous adjustments but then, even with NEF files, LR4 is now working fine as fast as LR3. After installing beta LR4 I've found that from this precise installation time, even LR3 is becoming more sluggish than before. I've also noticed a very long time to wait when switching from Library to Development module, back and forth (LR4, not LR3). This too seem to be right now with LR4, but I don't understand why ?

     

    Config is : iMac27 i5, 16 Gb, Radeon 4850, some external FW800 HDs. OS X 10.7.3.

    I have had a call back from Adobe support and there would seem to be issues with settings imported from beta and previous versions.  There advice and it worked for me to to remove the LR4 beta version with windows software then reboot your machine.  Then in windows 7 go to c:users/pc/appdata/roaming/adobe and then drag the lightroom folder to the desktop.  Then start LR4 and create a new catalog.  DO NOT IMPORT OLD ONE.  This will create a virgin set up.  LR4 on my machine now performs as well as LR3 did.  Have not yet loaded a old catalog from LR3 so hoping that will be OK

    After playing LR4 with speed improvement for the whole night. I find it is still smooth.

    All of you can check with the video in order to compare with yours.

     

    See description in the video for more information.

    Of course we cannot delete our existing catalogs and start new ones. That is not a fix.

    terry275's fixes are Windows-specific, fwiw: I use a Mac.

     

    This is a major drag, literally. Fortunately I still have LR3 installed, and only one or two catalogs 'upgraded' to LR4 slowness.

    AndyYau,

     

    I`ve watched your video, especially between 0:46 and 1:03, where you adjust the exposure slider. Would you call that smooth? Screen redraw looks very jerky. Or is it just your video recording? Is what you see in that video what you see on screen in this situation?

    If yes, it`s as jerky as on my PC. The means, you pull the slider, but what you see on screen is an update maybe two or three times a second.

    I have just verified with LR4 and also LR3.

    It is my hand, not LR4. I did not keep my mouse constantly moving.

     

    I think you do not encounter the slow issue of LR4. When this problem happens,

    your mouse is almost sticked to the slider. And every movement take 2-3 seconds.

    Andy, so it is smoother than what the video shows? I`m wondering, because the slider movement in the video seems much more constant than the screen update.

    Steven,

     

    You are right. Just compared with LR3 again and again. LR3 slider is faster and smoother. LR4 is slightly jerky if compared with LR3.

     

    But LR4 is now several times faster than when I just installed it. I almost cannot work with it as any adjustment takes 1-3 seconds for screen to update!!

    AndyYau : good video. Development time (from 1 picture to the other) seems to be 4 / 5 secondes. Same  with me (I had the same with LR3).

    BUT : Some users mentioned that they had about 0.1 s for that action !

    Of course you're right, Terry275; I didn't phrase it correctly. What I meant is that not having access to the older catalogs is the problem. All that work!!! Hundreds of hours.

    @AndyYau

     

    Thank you very much for the work, that you uploaded that video. I had a look at it in several quality settings. I can see clearly how your mouse mooves and how the picture updates. This is laggy as hell....sorry. Yes, maybe it is in your case as fast als LR3.6, but in my case lr3.6 works completely fluid....and my lr4 works exactly like i saw it in your video.

     

    So this is not fast......this is slow as it can be. not useable!

     

    King regards Frank!

    Frankc1978 : What I don't understand is that some people like AndyYau or me find the same results with both LR3 and LR4. Indeed, this is much slower that what you describe on your high end machine but there is no difference between the 2 versions. I would think that LR 4 would worse on LR 3 on all machines (not just on the high end ones). So , there might be an other reason.

    Now confirmed you can load old catalogs in LR4 after virgin start up and they do convert but run sluggish which is what adobe have identified and presumably are working a fix.  When you revert to the virgin catalog in LR4 and work on new imports via LR4 the software performs to LR3 speeds.

    Hi Frank,

     

    Fast and slow is relative and this is why I upload a video for us to compare.

     

    I think we have to seperate two cases:a

     

    1. When LR4 is normal (now on my Mac), it may be not as smooth as LR3. But the different is small. And I agree LR3 is a little bit faster.

     

    2. When LR4 is abnormal, it is serveral times slower than the speed shown in the video. (For example, when I move a slider, my computer CPU load is almost 100% for all 8-cores, and I need to wait 2-3 second for the screen to refresh for just ONE mouse action). The speed different is huge.

     

    It is pity that I do have have a video to show case 2. After Copy AS DNG, it seems problem of case 2

    is solved. But the inherent probelm of LR4 in case 1 is still there.

     

    So I think we are talking two different issues of LR4.

    @correspondanc & @ andyyau!

     

    You both are completely right. in your 2 cases maybe you are used to a slower speed even out of lr3. maybe lr3 always was a little bit slower, but as i said, in lr3 were people capable of investing money in good hardwere on so they got a really, really realtime and fluid workflow, like i have in lr 3.6. in this case you guys got a slower pc and a slower lr 3.6 and do/can not see a difference between lr 3.6 and 4.0. thats completely ok. but you must understand guys like me who are used to work on a realtime lr 3.6 and now work with this, that is just like got my 5 year older computer back. not even high end machines are able to make a fluid and real time workflow and that is my real problem. yesterday a saw lr4 on the most powerfull mac pro you can get for money. doing most profesional videocutting on it and very high complex renderings using the most expensive quadro fx card. lr4 was not slower or faster than on my machines. it is like tehre is a door in lr4 that is closed for fast machines. as i allready said on my 12 core (24 threads) machine i do not have more than 8% cpu usage so lr4 (x64) does not take the whole power a computer can deliver! working in lr 3,6 my cpu usage rises to about 36%. i will try the trick terry275 wrote above and see if it will bring any difference!

    Frankc1978 : I think we do not understand each other.

    I totally agree with you. When used to fluid workflow on your machine, going slower is not acceptable.

    What I don't understand is why on your machine you go slower (a lot from you say), and , on smaller machines, there is no difference (I calculated as I stll run with both). It does not make sense ! LR4 just also run at a slower speed on my machine too.

    My conclusion is that there is something different : graphic card, the way LR4 uses dfiferently some CPUs from some others. I don't know what it is but it is a combination of LR4 and the hardware.

    After two days struggling I have an LR4 running as fast as my LR3 (or if there is a difference I can't notice it).

     

    Struggling because I did not know you could not load the paid copy over the beta test copy. It was unuseable in that mode.

     

    If you have LR4 beta you need to uninstall it with Windows. You need to reboot. You need to remove all relevant .ldata and .lcat files and any LR4 catalogue folder. I also removed all the entries in the ...roaming/adobe/lightroom folder.

     

    If you re-install you need to build a new catalogue of course.

     

    If anyone around here from Adobe wants to claim my method is overkill then maybe the next person with problems will not to take such desparate measures - lucky them!

     

    I should have spotted the clue. I loaded my paid for version of LR4 on two machines yesterday. One worked a treat. One worked like treacle. The first had not been used for the beta test and the second had...

     

    All in the cause of progress. But at least my LR4 is fun to use again.

     

    Happy days.

     

    Tony

    Yes, thanks,

    I see the same thing here.

    Starting a new catalogue (no re-install) and doing a new import of the same pictures makes LR4 much more responsive.

    Activity monitor shows a much better balanced and overall lower load on the CPU cores when manipulating sliders in the develop module.

    While before the load on all CPUs would brickwall to the max when doing adjustments resulting in jerky slider movements, now all the cores have some headroom and slider movement is reasonably smooth. Pretty close to old LR3 behavior even with the new process.

    It seems like Adobe has to look at how to "upgrade" old catalogues without the speed penalty. Recreating the catalogues from scratch is obviously not an option for people with thousands of pics organized through LR.

     

    Now confirmed you can load old catalogs in LR4 after virgin start up and they do convert but run sluggish which is what adobe have identified and presumably are working a fix.  When you revert to the virgin catalog in LR4 and work on new imports via LR4 the software performs to LR3 speeds.

    Calculating status...
    Mar 8, 2012 8:53 AM   in reply to BCormier

    I haven't done any scientific test regarding this, but I have a dual screen setup and disabling the second monitor makes a very big difference. With both screens being used by LR4 any change to the RAW settings gives me a beachball. I turned off the second one and it feels much more responsive. I'm working on a Mac Pro, Mac OS X 10.7. Of course, disabling the second screen is not the solution. I still want to use both

     

    I have a medium-big catalog (about 60,000 photos) and it's impossible for me to reimport it: I use constantly virtual copies, and those will be lost (as far as I know) if I just reimport the original DNG/RAW. So that is not an option for me (and I'm sure for lot's of people)

    Hi All. Count me as grumpy for how slow LR4 is. I have spent about 10 hours fiddling including doing a complete system restore. I will report fidnings but here are system specs:

     

    i7 950 Quad core OC'd to 3.9Ghz - rock solid.

    24Gb RAM using Mushkin Black OCd to 1800Mhz - rock solid

    C: is RAID 0 on Intel Sata2 Controller, running two OCZ Vertex3 120Gb SSD

    Scratch drive is mushkin Max Iops 240Gb SATA3 SSD on SATA3 controller

    Photo directory is on 4Tb partition (two WD Caviar Black drives in RAID 0 on intel SATA2)

    Three displays but LR running on two - powered by two MSI GTX 570 cards OCd by about 20% - rock solid - have SLI disabled

     

    Both Lr3 and Lr4 repond much quicker when second display is turned off. Lr3 us easily usable with second display running - Lr4 is very sluggish.

     

    I have uninstalled. Reinstalled. Backup recovery. Lr3 only. Lr4 only. Side by side. Sharing catalog. Seperate catalog. Virgin import to LR4 to make brand new catalog. Does not matter - almost identical performance problem with LR4 (compared to LR3) under all conditions. Here is where I left it:

     

    I now have LR3.6 and LR4 in side-by-side installs with completely seperate libraries and referencing duplicate data on the same partition. Without a doubt, LR4 is much, much more slugish than Lr3. Here is the kicker: I created a 12Gb ram disk and copied one of my folders with RAW images in it. When reading these images, LR4 does move more quickly than when reading identical files off the RAID 0 photos drive. However, the improvement is nominal and remails, very obvioudly slugish. In comparision, LR3 reading the same files from the Ram disk is much faster - tiny bit of lag.

     

    The problems cannot have anything to do with hardware limitations or file sizes. There is something about LR4 that is grinding down its responsiveness.

     

    How could they not have noticed this?

     

    Kirk

     

    PS. Once an image is cached, LR4 much more responsive - still slower than Lr3, but usable.

    As an update to my previous post (#46), I tried terry275's suggestion of removing the lightroom folder and allowing LR4 to regenerate a virgin setup.  I then created a new catalog with freshly imported images.  Performance was the same - usable but not perfect with one display but very jerky with the second display enabled.  The second display is lagging far behind the main display - they don't change simultaneously like in LR3.  CPU spikes to 100% when the second display is trying to refresh.  With 2 displays enabled, LR4 is practically unusable.

     

    And, as someone else mentioned, recreating catalogs from scratch isn't a realistic solution for those of us who have spent hours editing, sorting, rating, and keywording images in our LR3 catalogs.  They need to convert properly.

     

    Out of curiosity, I installed L4 on a computer at work: Core i5, 4GB, Radeon 5450, Win7 Pro 64bit.  This machine is lesser spec'd than my home machine (i7, 12gb, Radeon 5750, Win7 Ult).  I created a new catalog and imported some raws. LR4 is much more responsive on this lesser machine than on my home machine, for some reason. It is smooth and snappy, like LR3.   With a second display enabled (as a window on the main display because this comp doesn't have two physical monitors), performance slows a tiny bit and the second display image lags about 1-2s, but this is much better than it is at home on my better computer.  On my less capable work computer, LR4 would be totally usable even with two displays.

     

    Differences: At work, LR4, Win, and the source images are all on the same drive wheras at home, the images are on a separate internal sata drive.  Work has a slower CPU and less RAM. Work never had LR4 beta installed (did have LR3), home did.

     

    Similarities: Same OS, both 64bit, both ATI video, both LR4 final, both new catalogs, same RAW files.

    Same slowness and spinning wheel with LR4. I just turned off my secondary monitor and closed all the panels in develope modular except the 'basic' and the speed seemed much improved.  But of course I want my secondary large screen display.  Hopefully there's a fix for dual screen users.

    I tried the route of virgin install after uninstalling the original LR4-over-Beta install, deleting all files and cache and  I restarted with a new, empty library.  I imported a few Canon RAW files and gave it a go - I see very little, if any, performance change.  I processed one of the same RAW files in 3.6 and it was very responsive with low latency.  Using similar edits, the export of the finished JPEG took about 16 secs in LR4, 8 in 3.6. 

     

    I'm going back to 3.6 until Adobe comes up with a solution.  I do this as a hobby for fun and LR4 is so irritating right now that it ain't fun at all.

    I just did fresh install of LR4 and LR3.6. I created two entirely new catalogs for each but importing the same 300 RAW images. LR4 is a little faster than before, but it is still much more slugish than LR3.6 in side-by-side comparison.

    LR4 seems to be a downgrade from 3.6. Definitely not what I expected from Adobe and from what I'm reading I'm not unique in my impression.

    I don't know if this is useful or not, but I thought that the 4Beta was a real dog, and I had uninstalled and reinstalled a couple of times.

    Today I decided to try the Lightroom 4,  so I unistalled the Beta again, downloaded and installed the full trial  version and again it opened the few photos I had in the catalogue, and again it was really slow, and used 100% of the cpu for most of the time it was trying to do any adjustment.Quite disappointing really.

    So I uninstalled, rebooted, reinstalled the trial version, found the Beta catalogue which was in Pictures as Lightroom 4 Beta.Ink, and all related files,Beta Ink2 and data, and I don't know which of the two things I did, rebooting after uninstalling, or removing the catalogue but now I have a Lightroom 4 which responds very well.

    Like I thought it should in fact.

    I'm also experiencing a sluggish interface. I'm using a 2010 6-core 3.33GHz Mac Pro with 24GB of ram and a 240GB SSD. LR4 is currently using about 3GB RAM. Slider movements take 1-2 seconds to show up on the 12MP Nikon D3s RAW preview in the Develope module. Even more curious, moving files within LR is extremely slow even when I'm not in the folder sending/receiving the files which would require a screen redraw for each move... but it acts that way... About one file per second moves between source and destination.

    I have a Mac Pro eight-core and find it way to slow also.

    If you look at the last three messages you will see the first (of the three)  removed all traces of the beta and now has a useable LR4.

     

    The next two messagers do not tell us whether they have upgraded from the beta or from LR3.

     

    I am sorry to labour this point but, to me anyway, it seems important.

     

    It really would help if future posters not only tell us about their slow LR4 but also about whether they migrated from the beta and/or LR3.
