Hey everyone. I hope someone can help me with this because I haven't found anything on Google. At least, nothing that works. When I first get to work in the mornings, the big banner files I have open very quickly. However, after about an hour goes by, Photoshop slows down and everything takes so long to open. Any ideas on what might be causing this and how I can fix it? Help would be greatly appreciated!
In the Preferences what are your Performance settings?
Do you have a dedicated scratch disk?
How many files do you keep open?
This sounds like a memory problem to me. Open Task manager and keep an ey on the amount of menory being used. Many programs 'leak' memory, taking up more and more voer time, even if the program is not doing anything! Firefox used to be really bad for this... Try always closing windows that you dont use, purging your memory, upgrading your RAM, increasing the free space on your HD (swap file) and adding an SD card to your PC (on Windows 7) for a memory boost .
Yup, definitely sounds like a memory problem, but if you post information about your system, OS, 32/64Bit, Photoshop version etc, someone may be able to give you more detailed help.
I'm assuming that MikeJones11x was talking about an SSD (Solid State Drive) in his answer above, and he's right, adding an SSD to a system with give you a huge performance boost, but you need to be careful.
Never use an OS/Apps SSD as your Scratch Disk; if you want your Scratch Disk on an SSD, install a second one, which is what I've done in my own system. Another thing to be wary of is the Controller in an SSD, depending on whether it's being used for the OS/Apps, or as a Scratch Disk.
This is a fairly complicated subject, and I won't go into any more detail in this reply, but if you'd like to investigate this further please either post a reply here, or e-mail me, I'll be glad to help if I can.
If you close then relaunch Photoshop does your fast performance return? That would suggest memory issues as suggested by other posters. If, however, your Photoshop performance remains slow after you close and relaunch it there may be other system problems. I've seen a significant slowdown in Photoshop and camera raw processor-intensive activity because of a failed CPU cooling fan. It appeared (thought I didn't confirm this) that overheat protection on the MB and bios reduced cpu cores processing rate to prevent damage. Long shot but might be worth a look.
