File opening and saving takes much longer in CS5 than in CS2, either from bridge, or directly in Photoshop.
Windows 7 64 bit professional pc
Intel Xeon W3530 @2.80ghx quad core
12 gb ram
total virtual mem 27.6 gb
Nvidia Quadro FX1800
seperate 50gb internal scratch disk
64 bit Photoshop CS5
Drivers and all Adobe products up to date
I have timed opening 10 5mb files and they all open 40 seconds quicker in CS2 running on an old dual core machine with just 4gb of ram than the machine listed above, which I had custom made by Cryo Performance Computing especially to run Photoshop.Saving is equally slow, and again much faster in CS2. Bridge is very slow too; selecting 1 file and then clicking to select another can take up to 10 seconds to respond, screen occasionally greys out
I have a seperate drive set up as a scratch disk that is solely used for that purpose, Photoshop is on a seperate drive.
Things I have tried:
deleted prefs file
uninstalled and reinstalled
updated all drivers
disconnected all external drives and printers
implemented all performance enhancements as listed by Adobe in the help section
disabled open GL drawing (no effect so now back on)
altered memory usage between 70% and 90%, no effect
Opened files from an explorer window, bridge and from network, no difference
Purged cache, optimized cache, deleted all thumbnails
Reduced history states to 50, cache levels to 2, tile size 1024k
General working on files is fine, opening and saving is the problem. Sometimes a single 5mb file can take over 15 seconds to open; on my old machine with CS2 its open in around 3 seconds. Saving in batching or image processor painfully slow.
Could changing the paging file size and or location help? I have had this problem since getting CS5, so its not something that has developed.
Sorry for the novel, but this is driving me mad as I use photoshop 10 hours a day 6 days a week, and it's just too slow.I really hope someone can help!
