Source was not originally written to take advantage of multiple cores for a single server instance. Over time, we have converted some parts of the engine to use additional threads/cores, but the majority of the engine can only use a single core at a time. That is unlikely to change for any of our currently released games, and the CPU usage of a single core will be the main factor for performance.
We have made improvements to performance in the past and we plan to continue making small improvements as we find them, but you should not expect to ever see a single CS:S or TF2 server use 100% of a quad-core system..

It has always bugged me, I had to set affinity to each core manually by an application. And server lags once a srcds instance hits 25%... Is there any solution to this problem?

(note: I don't know if setting affinities for srcds even handles properly and increases it's ceiling.) The srcds process is only allowed a maximum ceiling of 1 core, on my box once I hit 40 players on my Garry's mod server, the process is at it's top of that core, pushing 25%. Therefore it ends up getting automatically bottlenecked, once it uses that core you experience fps drops in-game to 10, which does effect gameplay. Why is this ceiling in place? Is there a way around it, does setting affinities per srcds process actually fix this issue, or is it still only reading 1 core max? My WS2008 runs the process at a consistent 33.03 fps until that ceiling gets hit. The image below is the core with 27 users online currently, I've also included an "rcon stats" log so that you can see the current fps. And see how full that core is becoming as more users connect. http://i54.tinypic.com/33az7sg.png 17:24:47 CPU In (KB/s) Out (KB/s) Uptime Map changes FPS Players Connects 0.00 70.07 269.64 1003 0 33.03 27 86 _______________________________________________ To unsubscribe, edit your list preferences, or view the list archives, please visit: http://list.valvesoftware.com/mailman/listinfo/hlds _______________________________________________ To unsubscribe, edit your list preferences, or view the list archives, please visit: http://list.valvesoftware.com/mailman/listinfo/hlds
