Step-by-Step Guide
1 Profile and Benchmark
Use tools like htop, iotop, and application profilers to identify bottlenecks. Dont optimize blindly - measure first.
Pro Tips:
- Focus on the biggest bottleneck first
- Set performance baselines
2 Optimize Memory Usage
Tune application memory limits, enable swap as a safety net, and ensure adequate RAM for your workload.
Pro Tips:
- MySQL buffer pool should use available RAM
- Watch for OOM killer activity
3 Improve Disk Performance
Use SSDs, optimize filesystem settings, and ensure adequate IOPS for your workload. Consider NVMe for high-performance needs.
Pro Tips:
- Enable TRIM for SSDs
- Use noatime mount option
4 Implement Caching
Use Redis or Memcached for application caching, enable opcode caching for PHP, and use CDNs for static assets.
Pro Tips:
- Cache database queries
- Use HTTP caching headers
