Improve your resource performance

In 2026 FiveM flags resources that run slow with a red warning every player sees. This guide teaches the patterns that prevent the warning - not by guessing, but by measuring. You will take a resource that triggers the warning, profile it, apply the right fix, and prove the warning disappears.

You'll build: A resource that passes the slow-resource warning check, with measured before-and-after proof that your changes work.
Time: ~25 minutes
You need: A local FiveM server, a resource you can edit, and F8 console access.
You'll learn: Distance checks, throttled loops, when Citizen.Wait(0) is fine vs when it burns CPU, and how to verify your fix with resmon.
