Been running a server for about a year now and have started to have problems with cpu usage roaring above 100% during a high player count. Tried to pinpoint the problem for months now and ended up concluding that it was the host's fault, so I migrated hosts. I had the same problem so now I'm sure that I've done something stupid and so here I am.

I've attached both my server.cfg and a vprof dump for anyone that can help me out. Had to zip the vprof dump since it was too big to post directly. The main thing I thought was strange was that SV_Frame was being called only once every other frame, which, of course, doesn't seem right.

Any help is appreciated.

Plugins ?
Have you tried run without MM:S and SM ?

What CPU ?

I tried unloading a few plugins during peak hours and that relieved some server strain. Had someone else look at the vprof dump and I've currently removed most of the plugins that use a SetTransmit hook.

I try to avoid doing too much work during peak player hours because I don't want to interrupt players while they're playing, but that's when the server lags so I'm a bit stuck between a rock and a hard place.

For CPU its AMD EPYC 7601, running a single core Linode VPS.

How many players are you talking about? That CPU won't handle more than 10 players on an 128t server, especially on a VPS.

Its 66 tick, and starts to lose framerate when player count reaches above 20 or so. Had the same issue on another VPS but I forget what processor they had. I didn't have this problem until a few months ago, however.
