    Slow, slow running Photoshop & Lightroom at the same time.

    Bent Nielsen Community Member

      Would like to keep my best pals Photoshop CS5 and Lightroom 3 open at the same time.  Having worked on a few images in LR3 and then in Photoshop, they both run progressively slower. 

      Photoshop Memory Usage set to 70%.  No other programs except Mail are open.

      Would love alternative to present solution which is to alternate between terminating the presently not used program, but this is awfully tedious.

          I'll second that!

           

          I'm running LR3 & CS5 on one of the latest model Intel Mac'Pro' 'workstations' (or so god-Steve likes to refer to his 'insanely kewl' 'top-o-the-line' computing products). And running these two apps (along w/iToons, Ffox, TextEdit and a few other minimally processor-hungry apps in the background) I find myself constantly waiting for them to do something – anything!

           

          My installs were each done correctly. I have 6 gigs of memory (1066MHz sticks!), a 'quad core' processor as conductor on this thing and then apps that have been optimized to run on this (64-bit) architecture run so pokey I feel like I'm working on an old G4?! (I'm not talking 'pinwheels' here folks, I'm watching Adobe's 'new' 'progress'-graphic spinning as PS is 'working'.)

           

          I know what the response would be if I'd call crApple'Care': "Oh, it's your Third Party applications. It can't be Snow Kitty! Archive and Re-Install." (Problem solved; next customer please...)

          But at the same time, if one were to call Adobe and be lucky enough to speak to someone who isn't answering from a hot, humid phone-farm in east India, instead (perhaps) get some mellow fellow up in northern California, we'd likely get the reverse: "Sorry Meester Mike. I'm not familiar with Mac computers. Perhaps you could call Apple and explain the problem to them? Adobe products are really quite stable and sophisticated and..."

           

          Sheesh!

            12GB of RAM.

             

            Seriously.  I've had LR & CS5 Photoshop EACH use up 3-7GB RAM alone.  Now add any other apps you might want to leave open such as web browsers. It adds up fast. These days web browsers can quickly suck up 1-2 GB RAM use. Then Add general OS needs, about 2GB overhead...

             

             

            Each application will run if you have 4GB of RAM.  And you'll likely see some free RAM left over and think you must have plenty.... Nope. The rest of the needed data is being used as a swap/page file on your system's hard drives. That's what causes the big slowdowns the majority of the time.

             

             

            However, I have noticed that using Local Adjustments in LR 3 is somewhat buggy.  After a few pictures LR gets slow and laggy for no real known reason. This on a 8 Core 2.26 with 24GB RAM. So I think there is some software bugs still in the system. Relaunching sometimes helps, until I work on a photo with heavy local adjustments done to it.

             

            You can never ever have too much RAM.
