Fix lag and low FPS on the server
Server FPS, entity counts and the plugins that quietly cost the most.
3 min read
Run server.fps in RCON. Healthy is 60 and above. Below 30 players feel it as delayed hits and rubber-banding.
- Entity count is the usual cause. Run entity.count — a month-old 4500 map with heavy building can hold hundreds of thousands.
- Decay and cleanup plugins reduce this by removing abandoned bases. They pay for themselves.
- Plugins that hook OnEntityTakeDamage or player movement run constantly. Suspect those first.
- A wipe resets everything and is the fastest way to confirm the problem is accumulated entities rather than your plugin set.
