Photoshop: resources and multiple user accounts (Mac)

  • Question
  • Updated 7 years ago
I use a shared computer at work (Mac Pro 6GB Ram, OS 10.6.8). Some of my preferences drive other users batty. For instance, Camera Raw open all TIFFS.

I'm thinking the best solution my be to have my own login account with fast user switching. This isn't something I have a lot of experience with, but I believe each account gets it's own preferences, workspaces, etc. Please advise if I'm mistaken.

We don't often close PS or shutdown the computer. My question is, how is performance affected when programs are left open on multiple accounts? I can close windows/files on the unused accounts, but would likely have PS, Bridge, Safari and Mail open on both. Does this effectively double the memory load and issues of memory leaks?

Edit: let me not confuse the issue with non-Adobe products. Never mind Mail and Safari. Just if Bridge and PS are open on both accounts.

Is this question better asked on the Apple forums?

Hi Scott,

Your question is more general. Every program running on your computer consumes some RAM. so the more the programs you run, the lesser it will be available for other programs.
If the program is not consuming too much RAM, then you wouldn't notice any difference even if both are running. Even in case of our products, the RAM consumption depends on what you are doing with the product. Your 6 GB RAM should run 2 instances of our products with out any performance issues. Again performance also depends on what other programs you are running and their RAM consumptions

Thanks,
Shashi

Shashi, thanks for your reply.

Let me try asking this another way. For the sake of simplicity, lets assume Bridge and PS are running but with no files or windows open. If they are open on two login accounts concurrently, is it doubling my RAM load? IOW, by having the two programs open on two accounts the same RAM hit as if 4 programs were running on one account?

Allow me to use hypothetical numbers. If just having PS and bridge running on one account (with no files or windows open) uses 2 GB RAM, does doing the same on two accounts use 4GB?

I know the actual resources required depends on which programs are running ans the size/number of open files and windows, etc. I'm just trying to get a handle on what's happening at a base level when the same programs are open on two accounts concurrently.

Thanks again.

Hi Scott,
It won't be doubled. Again, this question is related to Operating Systems, so I am signing off from this question.
Best regards,
Shashi
