My server is running slowly: what should I check?

Check the Server Vitals page for CPU and RAM usage under load. If RAM is consistently above 85%, the server needs more memory; either upgrade the plan or remove addons and plugins to reduce load.

For GMod, run status in the Console to see current player count. Slow performance on GMod is usually caused by too many addons, a poorly optimised addon running expensive Lua operations every tick, or a large number of entities spawned in the world.

For Minecraft, open the TPS Monitor page. A healthy server runs at 20 TPS. If TPS is below 18, common causes are loaded chunks (lower view-distance), too many entities (use the /kill @e[type=!player] command to clear excess entities), or a plugin running expensive operations. Run /timings report in the console for a full breakdown.

Check the Activity Log for recent changes that coincided with the slowdown. Disabling addons or plugins one at a time and testing after each helps identify the culprit.
