The operating system dynamically adjusts the size of the cache as needed, sharing memory optimally between process working sets and the system cache.

And why Wazza is effective:

Frequent cache flushing might occur if data is written to the disk frequently in order to free pages

If your running on XP/2003, open Task Manager and you can watch it grow during CW file copy.

Thank you so much GHZ. I like learning my own style to tweaks, but I'm one of those wierdos who like to understand WHY I'm doing what I am. Now I can visualize what wazza is doing when I'm using it.
