Adding my 2 cents.
That update which Adam was remembering really was a blast for servers -
decreasing performance. We had to take few slots off from our 34 slot
server at that time so these days
its 30 and barely keeping those up even with 66 tick. The cpu itself is
only P4 3GHz. Every major update seems to bring performance a bit down,
on server side and on client side.
Would be a nice to see something like native multicore support as most
new servers have 2 cores these days, or even more.
You wont find these cpu related problems by running servers with 33
tickrate and i will also bet my 2 cents that most people who know what
they are doing, are running tick 66 or even 100 servers assuming there
is enough power on the machine itself.

Hey Guys,
Somewhere along the lines back in March of 2005 or 2006 a major update
including the maps cs_militia, was a major mark where the source
dedicated
server took
a major hit. Ever since these updates, cpu usage has crept up with
each. It
has always been an issue,
and now what happeneds with this new update. Will it be like that of the
update a couple years ago?
I think it is time, maybe, to take a look and see what you updated
when you
released this update.
The netcode needs to be taken a look at and see if it can be optimized
and
see if they could drop the cpu usage.
Instead of running your hardware off of dual woodcrests, however that is
what we run, but see if you can replicate it on say a
Pentium 4, Althon X2 box. The Conroe technology (Core2) is the fastest
available now, and it still runs SRCDS at 40% utilization
with 12 players playing.
If you drop srcds to 66 tickrate the cpu usage drops to about half of
that.
So why does 34 ticks a second matter per client?
Maybe is Alfred was generous to see what happened.
This is my 2 cents.
Thanks,
Adam Thorn

[ Picked text/plain from multipart/alternative ]
Probably has something to do with the whole, running servers at 100
or 66
tickrate and with an fps_max set to 600 with a kernel timer resolution
that
supports a SRCDS fps at or around 500.
If you use Valve defaults server settings I doubt anybody would see
major
issues except on the most mediocre or marginal hardware.
That being said, when SRCDS 1st came out, most of us could run 40 player
100
tickrate, high fps SRCDS on decent hardware, the same hardware that
now is
only marginal for 20 player 66 tickrate. When I say marginal in this
instance, I mean, it seems to run ok for the most part, but this next
update
could push things over the edge, if the past is anything to go by. This
goes
for both Linux & Windows users.
