How to Optimize Your FiveM Server Performance in 2026

Why Server Performance Matters

Nothing kills a FiveM server faster than lag. Players expect smooth 60+ FPS gameplay, and poorly optimized MLOs, scripts, and server configurations are the top reasons servers struggle. This guide covers practical steps to boost your FiveM server performance in 2026.

1. Optimize Your MLOs

MLOs are the most common source of FPS drops on RP servers. Here is how to keep them running smoothly:

• Use optimized MLOs — Premium MLOs from reputable stores are built with performance in mind. Avoid free MLOs with uncompressed 4K textures
• Check texture sizes — Interior textures rarely need to be above 1024×1024. Use OpenIV to inspect and resize oversized textures
• Reduce draw distance — Set appropriate streaming distances in your YTYP files so MLOs only load when players are nearby
• Remove unused MLOs — Every MLO consumes memory even when no player is inside. Remove any you are not actively using

2. Script Optimization

Heavy scripts are the second biggest performance killer:

• Use resmon — The built-in resource monitor (resmon 1 in console) shows CPU time per resource. Anything above 1ms consistently needs attention
• Reduce tick rates — Not every script needs to run every frame. Use Wait() or Citizen.Wait() appropriately
• Avoid excessive database queries — Cache frequently accessed data instead of querying MySQL/MariaDB on every action
• Clean up threads — Kill unused threads and event handlers when they are no longer needed

3. Server Configuration

Your server.cfg and txAdmin settings directly impact performance:

• Set appropriate player slots — More players means more entities and network traffic. Match your slot count to your hardware
• OneSync — Use OneSync Infinity for the best entity streaming. It handles high player counts better than legacy modes
• Artifact version — Always run the latest recommended FiveM server artifact for performance improvements and bug fixes
• Hardware — FiveM servers are CPU-bound. Prioritize single-thread performance over core count. 32GB+ RAM is recommended for 100+ player servers

4. Database Optimization

A slow database means slow everything:

• Index your tables — Add indexes on frequently queried columns (citizen ID, character ID, plate numbers)
• Clean old data — Remove stale records from logs, inventories, and phone messages periodically
• Use oxmysql — It is the fastest MySQL resource for FiveM with connection pooling and prepared statements
• Tune MySQL — Increase innodb_buffer_pool_size to 70% of available RAM for database-heavy servers

5. Network Optimization

• Server location — Host your server geographically close to your player base
• DDoS protection — Use a provider with built-in DDoS mitigation to prevent disruptions
• Bandwidth — Ensure at least 1Gbps unmetered bandwidth for servers with 100+ players

Quick Performance Checklist

• Run resmon 1 and fix any resource using more than 1ms consistently
• Check total MLO count and remove unused ones
• Verify all MLO textures are 1K or below
• Update to the latest FiveM server artifact
• Enable OneSync Infinity
• Add database indexes on high-traffic tables
• Monitor RAM usage — restart if it creeps above 80%

Start with well-optimized premium MLOs and build from there. A clean foundation makes everything else easier to manage.
