Yes, 22 gig on a dual quad core mac pro. This machine flies doing everything else but when I had TimeMachine running it was bogville. I usually just have PS3, LR, mail, safari open on my machine...everything else I open, use and typically close. Sometimes I have more stuff open but not always simply because I don't use much more than those listed. I was using a firewire 400 external hard drive for backup to Time Machine. I had it set to backup every two hours as I recall and it may be that that was too often but on a day when I do five or six portrait sessions that wouldn't be extreme to make certain things are being duplicated. Good to know it does work well for other folks. I've hired a woman who will be doing my client retouching and I will likely give it another try for her workstation.

Which versions of PS and iTunes are you running? Is your Time Machine USB? How long as it been since you've quit Bridge and PS or restarted?

I haven't tried just emptying caches, but quitting PS and Bridge usually speeds things up an appreciable amount. > > On the other hand, if your Time Machine drive is USB 2, you could be suffering from that. USB writes packets of data to RAM before copying them to the attached drive. Firewire is a continuous stream without continuous addressing of the RAM at all. > -- > Emily L.
