Unimpressed Performance with 4 Cores

[pwrightfl]

I've been running SRCDS TF2 server on a Compaq Presario with fair to good performance until the latest update. I was able to see better than 800fps with few drops lower then 100, generally during map changes. After the update the server is practically useless with continuous performance drops to 10fps. I figured that I just didn't have the horse power to run the game any more. So I moved the game to a HP DL360 box, dual Xeon 64 bit 3GHz processors, expecting a big performance gain. Well I'm not seeing it. Its just as bad as the Compaq.

What I'm missing? Can SRCDS take advantage of 4 cores?

Since they introduced srcds_linux the Server became less stabel. Also Servertool (MM:S+SM) and their Plugins can be the problem. See if the drops still happen when they are disabled.

I see you are using one of my precompiled Kernels. Maybe you should try the 100Hz Version to increase the throughput. Also try running the servers with fps_max 500 or if you really need 1000 use +fps_max 0

Srcds can not tke all 4 cores since it is still singe threaded. So maybe one core is maxed out. Also an AMD 64 is not really good enough to run high and stabel fps. Here you really should not use 1000Hz with preemtion.
