How to Use resmon in FiveM: Find Laggy Scripts Before They Kill Your Server
When a FiveM server lags, most owners blame the host or the framework. Sometimes that is true. But very often, one resource is doing something expensive and dragging everything down.
resmon is the fastest way to find that resource.

1. What resmon shows
resmon shows how much time each resource uses. If one resource constantly sits at the top, it is a strong suspect.
2. How to run it
Open your server console and run the resmon command. Then watch how resource usage changes when players do normal activities.
3. What “bad” looks like
The biggest red flag is a resource that spikes when nothing special is happening.
Another red flag is a resource that slowly gets worse over time.
4. The safe way to fix the issue
Do not delete random files.
Disable the suspected resource and test again.
If the server becomes stable, replace the resource or update it.
5. Keeping performance stable long-term
Performance is a routine, not a one-time fix.
