Important information is:
1. what addons are being used,
2. what O/S,
3. what ticrate and
4. what fps_max
5. highres timer (win32) or 1000HZ linux kernal?
6. hltv/tv enabled? spectators?

also, bots on CS:S servers totally skew cpu utilization :)

for example (since I don't run a CS1.6 server):

for my HLDM server I use:
====================
XP Pro, 2.0GHz AMD 2600+ 512MB memory
+sys_ticrate 1000 +fps_max 1000 + highres timer
server runs typically at 512FPS with occasional spikes down to 320FPS

sv_maxrate 7500
sv_maxupdaterate 15

I get 9 players max on a 1.5M/320Kb dsl uplink

so that's 35.6kb / player max utilization
I don't allow snarks on my server which can easily double that number.

CPU utilization varies from map to map, worstcase is 50% with a full server.
CPU Utilization is easily controllable by changing the fps_max.

a good CPU baseline with my above ticrate and fps_max is 100MHz per player.
I ran the identical server on an 850MHz P3 for years and saw up to 80% cpu
utilization under the same worst-case conditions.

I only run metamod and botman's stripper2 addon.

In testing HL2DM I see much higher per-player uplink usage (around 52kb per
player)
in testing CS:S I see 42kb to 45kb per-player uplink usage.

I can only support 6 HL2DM players and 7 or 8 CS:S players on that same
1.5M/320Kb dsl line.

both HL2DM and CS:S servers were running at:
ticrate 100
fps_max 300
sv_maxrate 8000
sv_maxupdaterate 20

Subject: [hlds] Server requirements


I find myself being asked quite often about what CPU/net requirements it
takes to run a server. I have answers based upon our internal
playtesting but I would also like to hear what you guys use in the wild.

So, my questions are:
1) What speed CPU do you use for a 32 player HL1 server (CS 1.6)
2) What speed CPU do you use for a 32 player Source server (CS:S)
3) How much bandwidth per user do you allow for a HL1 server
4) How much bandwidth per user do you allow for a Source server
5) How much difference is there in these requirements for other mods?
