Since the last major update (188.8.131.52) the server performance and stability has increased significantly.
Especially servers with low AI count have a lot of resources left even under high load with 120+ players.
In fig. 1 shows the server performance with respect to the player count.
It shows that servers can run with 100 to 120 fps with the current maximum player count of 128.
Therefore it would be great if the player limit could be removed or increased by 64 players to a limit of 196.
