A profile-driven audit
I read your server under real load with resmon, sort by CPU time, and find the resources that actually cost you milliseconds. No guessing from a feature list.
FiveM server optimization
Optimization that holds at 1000+ players.
When a server stutters at peak, the answer is rarely a bigger box. It is usually a handful of resources doing too much work on the main thread, plus a content folder full of oversized textures. I profile the running server, fix the real offenders, and show you the difference in resmon.
The usual cause
It is your resources, not your hardware.
Almost every lag problem I get called in for traces back to code, not the machine. One resource with a loop that never yields, a database query that blocks the thread, a script firing a native every frame. A faster CPU cannot outrun any of those.
The other half is streamed content. On a server with a few hundred add-on vehicles, every player may be pulling several gigabytes of texture data, most of it 4K maps the engine throws away after loading them at full size. That shows up as stutter and slow joins.

What you get
An audit, real fixes, and the numbers to prove it.
Fixes at the code and asset level
Loops that never yield, blocking database queries, per-frame natives, oversized vehicle textures streamed to every client. I fix the cause, not the symptom.
Before and after you can read
You see the resmon numbers from before the work and after it. If a change does not move the milliseconds, it does not count as done.
How it works
Measure, fix, measure again.
01
Profile
I measure the running server under load and write down the biggest offenders by CPU time. That list becomes the work queue.
02
Fix the worst first
I work down the list at the code and asset level, re-measuring as I go, so the time goes where it actually helps.
03
Prove and hand over
You get the before/after numbers and notes on what changed, so your team can keep the server fast after I am gone.
Optimization, answered
Common questions.
My server already runs on strong hardware. Why is it still lagging?
FiveM script execution runs on one main server thread, so total cores barely matter. A single resource with a tight loop or a blocking query can stall that thread no matter how fast the box is. The fix is almost always in the resources, which is exactly what the audit targets.
Can you optimize scripts I did not write, or bought?
Usually yes. I can profile and fix most resources, including paid ones, as long as they are not fully encrypted. Escrow or obfuscated code limits what I can change, and I will tell you upfront if that is the case.
How big are the servers you work on?
From small RP communities to setups that peak past 1000 players. The bigger the server, the more the small per-tick costs add up, and the more a clean profile pass is worth.
I want to try it myself first. Where do I start?
Read the optimization guide. It walks through resmon, the common offenders and how to fix them. If you get stuck, or the hitches survive your own pass, that is a good time to bring me in.
Still hitching at peak?
Send me your server details and I will tell you where the time is going.
