I have no idea what the problem is, but when the server goes above around 12 players. Insane lag spikes occur and the result from stats shows the server CPU usage going above 100. At first, we thought this was our dedi - so we bought a new dedicated server with 32GB of ram and a Opteron 6 Core processor (I know SRCDS isn’t multithreaded). Yet the lag seems to be even worse now.
EDIT: Just quickly running through my code to make sure that something is not looping infinatly
EDIT: Looked through my code, disabled various parts of it etc, nothing seems to have stopped lag.
