I just recently purchased a g4 ibook 12" and love this machine.

I have a question however. After working on some rather large files in PS, i decided to check out some scratch disk options. I'm aware that the best performance option is to set the scratch on different physical volume. In the PC world, I would partion my drive and set up scratches from there. This worked surprisingly well.

My question is, after playing around a little bit, I created a new disk image through the disk utility and used that as a scratch. I did notice less slowdown in the os itself, but the new disk image would only pull 50 megs or so from PS Is this beneficial, will it actually free the os from the swapping that PS does?

What other options are available short of partioning the drive or using an external drive?

Just curious what other heavy PS users do for better performance on a book.

Thanks in advance.

Get as much ram as posible for you machine. I am using a TiBook with 1GB of ram and my wife has the same Powerbook with only 256MB and there is a big difference is proformance using the same applications. The one thing that I try to do is run Photoshop on the Dual on the desk as there is so much more the Dual can handle than a sigle processor.

again buy as much RAM as you can.

thanks for the reply!


Yes my ram is maxed.

Ill rephrase my question, is there any benefit to creating a few disk images and using them as scratch disks?

I suspect not, since you're still swapping data to/from the same physical hard drive.
However, if you want to be scientific about it (and it might be fun to do) you could run PS Bench with disk-image swap against standard Photoshop-default swap and see which is better.
If you do, post your results
