WordPress on Nginx on Dreamhost

Running WordPress on Nginx via Dreamhost VPS improves resource efficiency and page load times compared to Apache, but requires upfront configuration. Nginx handles PHP differently, lacking .htaccess and mod_rewrite support, thus necessitating custom configurations for pretty permalinks and caching plugins. Key configurations include directives for content handling, cache rules, and error troubleshooting. Backing up existing setups and understanding Nginx's syntax is critical for a smooth transition. Proper pre-configuration ensures a seamless switch from Apache to Nginx, enabling improved performance for WordPress sites.

Time To First Byte: Beyond Server Response Time — Smashing Magazine

TTFB (Time to First Byte) is crucial for web performance, measuring the time from navigation to the first byte of HTML response. It includes multiple components: redirects, server connections, and request times. Improving TTFB involves optimizing DNS lookups, TCP connections, and potentially using a CDN to minimize latency and enhance user experience. Reducing server response time alone is often insufficient; real user monitoring can provide insights into specific delays, helping to address issues effectively.

WordPress and Web Servers

WordPress functions as a web application on web servers, primarily using the LAMP stack (Linux, Apache, MySQL, PHP). Web servers serve web pages and utilize software like Apache or Nginx to handle requests. Configuration allows multiple sites on one server through virtual hosts (Apache) or server blocks (Nginx). Upon user requests, PHP processes data, often fetching from a MySQL database, and returns HTML, CSS, and JavaScript to the user's browser for display.
