disk cache & memory utilisation


When I boot my 32 meg machine, I find that it has used about 16 meg pretty
much immediately.

I understand that a certain amount of this 16 meg is used by the file system

Is the amount of memory used by the file system cache adjustable? If yes,
where and how? Is the file system cache dynamic - i.e makes memory
available to applications if needed?

Where can I find and adjust virtual memory configuration information? Has
anyone got any good tips for configuring RTP to save memory?
