Adjusting the disk cache
The disk cache is memory set aside to help programs work more
quickly and efficiently. But the memory in the disk cache is not
available for opening programs or documents. If you often want
to open more programs than memory allows, you can set the disk
cache to a smaller size.
You set the size of the disk cache in the Memory control panel.
1. Choose Control Panels from the Apple (K) menu and
open the Memory control panel.
2. Click the up or down arrows next to the Cache Size
box.
3. Choose Restart from the Special menu.
