Hi Randy, and thanks for your reply :) By memory cache I wanted to mean the system´s file cache in the physical memory (pm) space. Like, when you execute a program it is loaded into the pm. When you close the application the files won´t go totally out of the pm, they go to a place called 'Cache' located in the pm. The disk access time is much bigger then the memory access time, so, this technique is implemented on linux (Mandrake, redhat,.. etc.) so that less disk access time is spent. This very nice if you have a large pm space. So, more cache means less free memory. You know?
My machine is a pentium II 333MHZ with 128 mb RAM, and for the 'RAM' reason, I want to limit the cache space in the pm. By default, Linux is forced to take all the space he needs to cache. wen it is over, swap runs on. I would like to control the cache space. thanks for your answer and sorry about my bad english. :) fred. >From: Randy Kramer <[EMAIL PROTECTED]> >Reply-To: [EMAIL PROTECTED] >To: [EMAIL PROTECTED] >Subject: Re: [expert] how to free cache from physical memory space? >Date: Mon, 22 Oct 2001 11:20:34 -0400 > >Fred Biehl wrote: > > I want to (more like 'need to') limit or maybe close the file system´s >cache > > in my physical memory space.
