FiveM Script Performance: How to Read resmon Before You Buy

What resmon actually measures

resmon reports how many milliseconds of the client's main thread each running resource consumes per frame. At 60fps a frame lasts about 16.7ms — every script on your server shares that budget with the game itself. A single resource idling at 0.30ms sounds harmless until you multiply it by the forty other resources doing the same thing, at which point your players' frame time is going to scripts instead of rendering.

Two numbers matter: idle cost (what the resource burns when nobody is using it) and active cost (what it burns mid-interaction — a menu open, a job loop running, a garage list rendering). Sellers who quote one number without saying which one are telling you very little.

The budgets that separate engineered scripts from ports

These are the budgets we hold our own products to, and they're achievable with ordinary discipline — event-driven logic instead of tick loops, distance-culled interactions, and NUI that sleeps when closed:

• Idle: 0.00–0.02ms. A script doing nothing should cost almost nothing. Persistent tick loops that poll every frame are the usual offender.
• Active: under 0.10ms sustained during normal use.
• Spikes: brief spikes during heavy operations (opening a large UI) are normal; sustained elevation after the interaction ends is a leak.
• Server side: steady-state near 0.00ms with cost proportional to actual player actions, never to player count alone.

Why most sellers don't publish numbers

Publishing a measured number is a commitment — it names the artifact version, the framework, the test conditions, and a date, and it invites every customer to re-run the test. A seller who publishes resmon receipts is accountable to them. A seller who doesn't is asking you to take performance on faith, usually behind escrow where you can't inspect the tick loops yourself.

Our position: performance claims without method and date aren't measurements, they're marketing. That's why every Vice Drip listing shows either a dated measurement or an explicit [MEASURED-PENDING] label — never a target dressed up as a result.

The 10-minute pre-purchase test

If a seller offers any trial, demo server, or open-source component, run this before paying:

• 1. Load the resource on a clean test server (default cfg, latest recommended artifact, your framework).
• 2. Open the F8 console and run resmon 1. Sort by CPU.
• 3. Record the idle value with no interaction for 60 seconds.
• 4. Use the resource hard for two minutes — open every menu, trigger every loop — and record the sustained active value.
• 5. Stop interacting and confirm the value returns to idle within seconds. If it doesn't, something is still ticking.
• 6. Note artifact version and framework — numbers only compare within the same conditions.

How Vice Drip publishes performance

Every product page carries a performance block. Values appear in one of exactly two states: a measured value with its date and method, or [MEASURED-PENDING] while our client-side measurement pass is still open. We also publish non-resmon engineering evidence where it exists — for example, VF Banking's money-integrity results: a 20-concurrent-transfer race test producing exactly 1 success and 0 duplicates with a 584-row audit ledger verified symmetric (measured 2026-07-05), and ten kill-mid-transfer crash cycles reconciling to drift = 0 (measured 2026-07-06). Those are the receipts we'd want as buyers, so they're the receipts we publish as sellers.
