Using resmon

This guide walks through Using resmon from preparation through verification, with a rollback path and the checks that matter in a real fivem servers environment.

Measure first

Do not optimize from guesses. Reproduce the problem with a stable player count/scenario and record server/client symptoms.

Isolate

Use resource monitoring/profiling tools and logs to identify the resource or operation consuming time. Compare idle and active behavior.

Common causes

Look for tight loops without appropriate waits, repeated database queries, oversized payloads, excessive entity creation, unnecessary NUI updates and log/event spam.

Change one variable

Optimize one hotspot, restart/retest under the same scenario, and compare measurements. Keep the previous version available for rollback.

Production validation

A change is not proven by one developer client. Test reconnects, multiple players, peak-use features and a full cold boot.
