The server has TWICE as much memory, and probably doesn't run Open
Office. Squid can be a memory gobbler, but that is configuration
You asked this the other day. Did you miss my response then? I'll
repeat it below, just in case. In the last message, you mentioned Open
Office, which you omitted to mention above. Certainly 256M RAM is a bit
low to run OOo and KDE 3.2 and whatever other applications without
running into swap.
------------- My last response
RAM, RAM, ramity RAM. The box in question doesn't have a load of RAM
(in terms of running KDE and OOo), and as time goes by in KDE more and
more memory is used, and hence more and more swap (reboot the machine,
and watch the swap usage (top works nicely, but there may be a KDE
graphical thingy too) as the machine is used for a while).
This is an issue with the 2.4 kernel, which will use swap rather than
reclaiming pages from applications, although this often leads to poor
application performance. With 2.6, you can adjust some kernel
parameters which control the kernel's 'swappiness' and can improve
perceived performance in such situations.
The solution is to buy some more RAM for the client, or use 2.6 and
play around with the 'swappiness' parameters.
