Ensure that your server's operating system and all installed software are up to date. Use the package manager for your distribution to apply updates regularly.
Implement caching mechanisms to store frequently accessed data. Tools like Varnish, Memcached, or Redis can help improve response times.
If you're using a database, optimize its performance. Regularly clean up unused data, use indexes, and consider caching query results.
Enable gzip or Brotli compression for web content to reduce the amount of data transferred between the server and clients. This can significantly improve loading times.
Adjust the server configuration parameters based on your hardware specifications. This includes settings like the maximum number of concurrent connections, timeouts, and worker processes.
