need some help sorting out performance issue

My problem is that my servers lag very often when about 10 people play and some complain about high ping.

Server specs:

Ubuntu 8.04 x86_64
AMD Athlon™ 64 X2 Dual Core Processor 5600+ (2900 MHz)
8 GB DDR2 800MHz RAM

100/100 mb line

I run 2 servers. One war server and an surf server.

The servers run at about 2% of the cpu when idle and about 5-10% when used.

War server:
16 slots
100 tick
sv_maxrate 20000
sv_minrate 15000
sv_maxupdaterate 100
sv_minupdaterate 10
fps_max 300

Surf server:
20 slots
66 tick
sv_maxrate 20000
sv_minrate 15000
sv_maxupdaterate 66
sv_minupdaterate 10
fps_max 300

I'm not a pro at server settings at would really like some tips on how to improve server performance and get rid of lag and ping spikes.

Thanks in advance for any help Big Grin
The ping problem is probably related to your internet service provider. (change to a better one if possible)
The lag could be kernel/hardware/isp related. If you have a router test bypassing it and see what happens.

The cvars on your servers shouldn't create any lag, but they aren't optimal either.
I recommend for the war server you change to sv_maxrate 35000 and sv_minupdaterate 70.
For the pub server, to allow sv_minupdaterate 10 is kind of low... force it at least somewhere above 30.

btw. Why not forcing the sv_max/mincmdrate's too? (set them the same as the updaterates)
"the box said 'requires windows xp or better'. so i installed linux"
Linux Ubuntu 9.04 Server 2.6.30-vanilla #1 SMP PREEMPT x86_64
the net is not a problem.

My server is hosted by

As for the rates settings. I've changed them to:

sv_minrate 10000
sv_maxrate 30000
decalfrequency 10
sv_maxupdaterate 101
sv_minupdaterate 35
sv_MinCmdRate 35
sv_MaxCmdRate 101

It seems to work good.

Now the only thing i would want is lower latenzy, but i don't think that is possible.
