I've never bothered tinkering around with FPS settings; does it really make
all that much difference? (I've never found it so)

Subject: Re: [hlds_linux] [hlds] srcds CPU usage, again.
I'm interested in hearing more performance data points. I can't find any
useful information on the web aside from really bizarre speculation from
people who have no business commenting on server performance.
On a Xeon 3060 (2 2.4GHz cores) with 2GB running CentOS 5, I can run, at
most two full 32-person TF2 servers. CPU usage on each core hovers between
65% and 90%, precluding my running additional servers on the same machine.
I'm disappointed with that, but I have little else to compare it to.
On a prior server, I was unable to run two full 32-person servers on a 3040
(2 1.8GHz cores) without substantially degrading performance, but I could
run 32 and 24.
I should also note that via "stats" (on the 3060), I see the FPS typically
average in the 60s on the full 32-person server.
I'd appreciate similar information from other admins. I'm also interest in
comparing bandwidth consumption. With two 32-person servers full around the
clock (and sv_maxrate 30000, if that's a factor), I use nearly 2TB a month.
*Please keep this discussion in the hlds_linux list*. There's too much noise
in the main list.
