So I think I may have brought this up before on this forum and I apologize if I already have. But the server needs to have regular map changes. Since there is no time limit on the map, the map goes on forever and it makes the server extremely laggy. Source is not built for that. You can make the server do map changes to the same map, just make the time limit like 12 hours or something if you don't want map changes. It won't interrupt rounds in progress.
