Speeding Up VPS on Linux and Windows

System Resource Optimization

Update OS and packages. Regularly install updates to patch vulnerabilities and improve performance.
Remove unnecessary components. Clean up unused libraries and utilities (apt-get autoremove, yum remove).
Disable unused services. Keep only the services that are truly needed.

Web Server Configuration

Apache:

Enable mod_deflate for data compression.
Use KeepAlive to reduce delays on repeated connections.

Nginx:

Enable gzip to compress traffic.
Configure static file caching to lower server load.

Database Optimization

MySQL / MariaDB:

Set innodb_buffer_pool_size to 60–70% of RAM.
Enable query cache (if supported).
Analyze slow queries with slow_query_log.

PostgreSQL:

Configure shared_buffers at about 25–30% of RAM.
Use work_mem to improve performance of complex queries.

Caching for Better Speed

Opcache (PHP). Reduces CPU load by reusing compiled code.
Memcached or Redis. Store frequently used data in memory for faster access.
CDN (e.g., Cloudflare). Reduces the number of direct requests to the VPS.

Performance Monitoring

For quick checks, use htop, iotop, vmstat, sar.
For advanced monitoring, set up Netdata, Grafana + Prometheus, or Zabbix.

Useful Tips

Use swap, but don’t rely on it as RAM replacement.
Perform regular backups to avoid data loss.
Optimize application code and SQL queries.

✅ Conclusion

Boosting VPS performance requires a systematic approach: fine-tuning the OS, web server, databases, and caching. Continuous monitoring helps identify issues in time and resolve them efficiently.
