Understanding server performance
What is server performance?
An Arma server is an instance of a game without rendering, hence it can perform better in comparison to game clients even on the same hardware. Much like the client, a server's performance is evaluated through means of frames per second (FPS), though on a server "a frame" would typically mean the amount of "game world updates per second.", A concept similar to "tickrate" used in some other games.
Why care about server performance?
In modern versions of Arma, server FPS no longer directly affects client FPS. However, server performance remains critical to maintaining a smooth and enjoyable gameplay experience. Poor server performance can lead to:
- Bad hit registration: Impacts the accuracy and reliability of weapon fire.
- AI/Vehicle teleportation: Causes erratic movement of units and vehicles.
- Connection stability issues: Results in lag and disconnects for players.
What affects server performance?
Various factors can affect server performance significantly. The following factors reduce the number or frequency of server-intensive processes, leading to better server stability and gameplay experience:
- Entities spawned: Frequent and/or large-scale spawning of units or objects.
- AI units: Great numbers of AI-controlled characters.
- Vehicles: Especially when moving or active.
- Static objects: Too many decorations or functional objects.
- Exploding munitions/submunitions: Explosions or ammunition that have fragmentation or secondary effects.
- Scripted audio: Particularly dynamic/moving audio scripts.
