Re: [SuSE Linux] swap partition and multitasking
Hi I have noticed the same thing although I have not got a fix. Have you know discovered a fix or reason? Thanks Rich
When I run multiple applications I notice that performance suffers greatly and my swap partition is barely being utilized.

Sounds like you guys have a hardware bottleneck somewhere. I find that I can run many applications without any slowdown whatsoever. I could do this on a Pentium 120, and now on my Celeron 300A. I get a slowdown when I am over using my swap partition and switching between applications. Another thing is if you haven't recompiled your kernels to optimize it to your hardware, it is going to be a little slower. Now I haven't really seen any adverse effects, any problems or any great speed hits from using the packaged kernels, but it is something to play with. It sounds like you are running on an older system, and you are having a problem with your RAM, you can try compiling the kernel to think that it can only allocate the first 16 Mb of RAM. Older RAM can cause slowdowns when you put too much in. You'll start using a lot more swap, but the multitasking speeds should improve. If you're still having speed problems, you might just want to look into a system tuning handbook. There are a lot of little tweeks you can make to your system to make it go faster. O'Reilly has a book about it in their Nutshell handbook series. There are definately others out there too. -----BEGIN GEEK CODE BLOCK----- Version: 3.12 GCS/M/>P d-(pu) s+:- a17>?

I am running an AMD k6-2 300mhz and 64mb SDRAM at 100mhz...I will try experimenting with the kernel. Thanks
