Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

I experience very poor system performance when running programs that need a lot of memory.
Open Office start up e.g. takes 2 minutes, and opening a small document in it takes cca. 30 seconds...
I have only a P233 machine with 64 Megs of memory, but the same programs show much better performance in windows.
I suspect that the poor performance in Linux may be due to the extensive, unreasonable use of the disk cache memory.
So far as I can judge, Linux uses the disk cache even when there is plenty of free physical memory to use.
An example: I see that the system uses 28M disk cache, when there is 38 M free (cached) physical memory.
Is there a way I can change the memory-handling policy of Linux to use the disk cache only when there is no free physical memory?
Distribution: DEBIAN! - (also used: Red Hat, Mandrake, Slackware, SuSE, BestLinux, EasyLinux, muLinux...)
Originally posted by J_Szucs I like KDE and I would prefer to keep it.
First I would like to know if the memory management policy can be optimized in Linux.
Everything can be optimized, you can start by optimizing the way you use your linux box . clean up services, recompile kernel, but also get more RAM, *get rid of KDE...*. Well if you absolutely want KDE try not to load to many stupid unnecessary things like fading menus and other useless s***t (4 example screensavers)
