source engine High Performance Config

[Roy 10,816]

Hello everybody, I would like to post a "high performance" configuration file for users wanting to set up game servers on the Source Engine (e.g. CS:GO, CS:S, etc). These are the same settings most of the GFL servers use.

sv_maxrate 0
sv_minrate 75000
sv_maxupdaterate 128			// Should match the tickrate of the server (e.g. Set it to 64 if your server is 64-tick).
sv_minupdaterate 128 			// Should match the tickrate of the server (e.g. Set it to 64 if your server is 64-tick).
sv_maxcmdrate 128				// Should match the tickrate of the server (e.g. Set it to 64 if your server is 64-tick).
sv_mincmdrate 128 				// Should match the tickrate of the server (e.g. Set it to 64 if your server is 64-tick).
net_splitrate 4					// Increases CPU usage but decreases choke.
sv_force_transmit_players 0
sm_cvar net_maxcleartime 0.001	// Requires SourceMod or similar for some games. Decreases choke.
sv_parallel_sendsnapshot 1		// Enables multi-threading. More info can be found here - https://github.com/ValveSoftware/csgo-osx-linux/issues/1492#issuecomment-450030374
net_splitpacket_maxrate 256000 	// Helps reduce choke on spikes of traffic. Not available in CS:GO.

 

Feel free to put this in your server.cfg (or you can create a file such as "rates.cfg" and put it in there, afterwards, just put "exec <filenamewithoutextension>" in the server.cfg).

 

I hope this helps! I will add documentation later!

 

Thanks.

Why use sm_cvar to set a server cvar rather than just setting the cvar in the config like the others?

I know I am a few months late to this question, but I would like to answer it anyway. There are "hidden" ConVars that cannot be changed directly (prints out an "unknown command" error if attempted).

 

Using sm_cvar bypasses the hidden flag (FCVAR_HIDDEN). 

 

In this config, net_maxcleartime is a hidden ConVar. Therefore, we had to use sm_cvar to change it.

 

P.S. I still plan on adding documentation to this performance config and I believe I've found other settings to improve server performance.

Thanks!

I've added the net_splitpacket_maxrate CVar to the config since this is very useful for reducing choke for non-CS:GO game servers (mostly when there are bandwidth spikes such as going through an area portal).

 

Thanks.
