Swap usage

Swap usage

[Mario Ohnewald]

Hello!
I am running Kernel 2.4.21 on a unstable Debian box. I have included my IDE
Chipset driver
I have just ONE game server on it and do not use that box very much,
although, it uses its swap space for some reasons.

load average: 0.00, 0.01, 0.00
Mem:    249136k total,   153572k used,    95564k free,    23636k buffers
Swap:   512024k total,   143652k used,   368372k free,    24500k cached

# hdparm -t /dev/hda
/dev/hda:
 Timing buffered disk reads:  150 MB in  3.01 seconds =  49.83 MB/sec

How can i find out why it is using so much swap, and how can i prevent it
form doing so? 
This swap usage makes my box very slow.

Cheers, Mario

I can only suggest you to try on this machine the 2.4.23-pre9,
it should really improve the VM.

Ciao,
               Paolo

Will the new 2.6.0 test9 solve this problem, too?
