So if we jump this up to 2GB of RAM (we have 1GB now), you think we'll
be in better shape? Enough to be able to run 3-4 HLDS (pingboost 2 and
500fps)?
Thanks Sid!

The performance problem does not look to be due to high CPU load.The
first line of vmstat shows the utilization over the life of the machine.
The server averages 13% (sy + id) load. With the two servers running, it
shows 22% load, lot's of headroom. The wait state percentage (wa) is 0,
so the system is not hanging on I/O.
Memory looks more likely to be the problem. The six hlds processes are
consuming 66% of memory. My math skills say starting another game would
consume 99% of memory and leave little space available for buffering
maps and such. Doubling or tripling the amount of memory in the system
would let it run four to six servers, given the CPU utilization.

At the moment, the 3rd server isnt running (because preformance is too

I'll turn AMX off in the metamod config and see what affect it has :).

More information is needed to diagnose the performance problem,
Run a "vmstat 1" for about 10 seconds while the three programs are
running and post the results.
Also do a "ps vax" and post the results from that. With the output from
those two programs, I can see whether it is CPU or memory bound.

Hi Guys,
At the moment we have a machine with the following specs:
Dual Xeon 2.8GHz (HT enabled in the kernel)
1GB RAM
74GB 10k RPM SCSI Hard Drive
I'm running 2.6.12 kernel with the hz/user_hz tweak (=1000).
At the moment we have 2x 12 man privates that are full 100% of the
time. These are running with pingboost 2 and sys_ticrate 500. FPS on
these two servers is almost always 500. System load is around 1.0.
However, when we attempt to run a 3rd HLDS with the same
pingboost/ticrate settings, FPS on all 3 servers drop significantly
(and
randomly) below 100. Load hits about 2.10. When we kill the 3rd
process,
load drops back to ~1.0 and we get 500 fps on the other two servers
again.
We are under the assumption that the processor can handle 3
instances of HLDS without a problem. But we're not sure why this 3rd
HLDS process is making such a big difference in game server
performance.
Does anyone have any ideas? Is it the RAM? Have we configured the
kernel
wrong? Any suggestions would be very helpful!
Thanks!
