New ACR still have very very very slow and ineffective engine. My PC have 32 Gb of RAM and when I open 2000 RAW files - I see that 15% of ram used 85% is free. There is lags when make exposure or sharpness tweaks. And red eye remove is bold and unpredictable - and still there is no manual mode for it. And missed manual mode for chromatic aberration - auto is not 100% adequate. And saving is very slow too - and I can even play WorldofTank during it - because it takes only 40 - 60% of my 3770K CPU. ACR 6 saving was much faster - it used 98 99% of CPU and made 4 files in row

P.S. http://ozerovpaparacci.photofile.ru/ - my galleries if somebody whant to ask why so many foto in time.

The main reason I use camera raw is for speed, it more closely meets my needs for ease of use when working in a production environment. I find though that 7.1 is slower in a few areas but does seem better in others.

Creating selective adjustments seems to be offering slightly less lag.  I have although found that if I jump to another image too quickly the adjustment I have just made on the first image has now been added to the new image. In the worse case I am selecting all images the change is made to all images.

Multicore processing seems to be what is affected here not memory, at least when saving images. Using Activity monitor I am noticing that 7.1 briefly jumps to using over 500% cpu and then quickly drops to 103% and varies very little until all the images has been saved. CS5.1 used to be very efficient in this. I can't tell you how much because I removed it thinking everything would be peachy... It's not.

While doing adjustments in 7.1, activity monitor is showing over 600% usage GREAT that's what it should be doing.

This MBP is no slouch, it used to be fast but 7.1 is defineatly slower at saving images so much so that I may have to go back to 5.1

Is ACR 7.1 usable on any current Mac? - It's dog slow on my Mac mini (2.7 i7, AMD graphics, 16Gb ram). Maybe Jeff Schewe is right and we'll have to wait until computer technology catches up with the software...

Do you get that with 3 x 11 GB DIMMs?    I assume it's a typo.

In all seriousness, Adobe:  Why haven't you continued to address this issue? 

Adriana commented early on, but then....   Nothing. 

A "we've reproduced it" would be great, but even a "we hear you and we're continuing to look into it" would be welcome, I'm sure, to the folks who are unable to use the software until you fix it..

I assume Adobe has allocated more resources to their subscription license (i.e., more/new features, more income), and don't have enough time to address existing problems with the software that people already paid for.

Looks like ACR 7.2 hasn't helped our problem.

I posted in the photoshop feedback forum here. Screen shots included.

Please chime in to make your issue heard.

These will give you a visual idea how the various versions multi-thread (yeah, I know, quite likely more detail than you wanted to know).

Well...  Not exactly.  In my case 7.1 and 7.2 clearly are busying a lot of logical processors, but not all  - as 7.0 did.  Look carefully at all the little graphs - something like 7 of them have gone unused in 7.2. 

But just to complicate things, if I open one image, interactively, the doggone thing DOES seem to use all logical processors!  This is just weird.

I haven't timed opening the files through the 2010 process, but conceivably it's possible it will execute fewer instructions to get the job done.  It would be worth a try.

For the first time ever I have rolled-back to a previous version of Camera Raw. I'm now using 7.1, as 7.2 was proving painfully slow in Bridge batch operations, as well as rendering to Photoshop. Quality seems good enough, but it's just too slow to get things done.

Windows 7 64b, Intel Core2 Duo @ 3.55GHz, 4GB RAM @ 1066GHz, P45Express/ICH10 RAID. Not cutting edge, but not past it neither.
