⚡ Performance Optimization - QBCore Guide for FiveM
Introduction
This tutorial turns ⚡ Performance Optimization into a clean, developer-friendly guide for QBCore/FiveM. You will follow a step-by-step flow, copy the relevant code patterns, and learn the “why” behind the setup.
Requirements
- QBCore installed and running on a dev server
- Basic Lua knowledge and comfort reading FiveM patterns
- A test workflow for iterating safely (dev server, not production)
- Optional: a code editor with Lua/FiveM helpers (VS Code recommended)
Step-by-Step Guide
Step 1: Performance Overview
In this step, you will apply the performance overview concept as a practical change: define the pieces, wire them together, then verify the behavior in your dev server.
Step 2: Key Performance Metrics
In this step, you will apply the key performance metrics concept as a practical change: define the pieces, wire them together, then verify the behavior in your dev server.
Step 3: Quick Performance Checklist
In this step, you will apply the quick performance checklist concept as a practical change: define the pieces, wire them together, then verify the behavior in your dev server.
Step 4: Immediate Optimizations
In this step, you will apply the immediate optimizations concept as a practical change: define the pieces, wire them together, then verify the behavior in your dev server.
Step 5: Advanced Optimizations
In this step, you will apply the advanced optimizations concept as a practical change: define the pieces, wire them together, then verify the behavior in your dev server.
Step 6: Common Performance Bottlenecks
In this step, you will apply the common performance bottlenecks concept as a practical change: define the pieces, wire them together, then verify the behavior in your dev server.
Step 7: Resource-Related Issues
In this step, you will apply the resource-related issues concept as a practical change: define the pieces, wire them together, then verify the behavior in your dev server.
Step 8: Server-Level Issues
In this step, you will apply the server-level issues concept as a practical change: define the pieces, wire them together, then verify the behavior in your dev server.
Code Example
# Server console commands
resmon # Resource monitor
status # Server status
citizens # Player count and detailsTips & Best Practices
- Keep authority on the server: validate inputs before money/database operations.
- Start with one resource/module at a time, then refactor after you verify it works.
- Use callbacks for request/response flows and events for push/UX updates.
- When you run loops, avoid freezes: always yield with Wait() (client/server) and cache hot values.
What You Will Learn
This Optimization tutorial focuses on practical outcomes for FiveM scripting and QB Core development. By following the steps in ⚡ Performance Optimization - QBCore Guide for FiveM, you will understand how the topic fits into a real server workflow and how to apply it safely.
You will learn the reasoning behind the implementation choices (especially for advanced topics), so you can make the same decisions again for future resources. The goal is to reduce trial-and-error, improve consistency across updates, and help your team ship changes without breaking gameplay.
- Identify the correct use case for this approach in a QB Core or FiveM environment
- Implement the key concepts with an install-ready workflow
- Validate compatibility and avoid common setup conflicts
- Apply best practices to keep your server stable over time
Why This Matters
When scripts, configs, and documentation are aligned with your server architecture, you reduce maintenance overhead. That means fewer upgrade surprises, faster onboarding for new admins, and a more reliable experience for your players.
