Time to First Byte (TTFB)
Time to First Byte (TTFB) is a foundational web performance metric that measures the duration between a browser requesting a web page and receiving the very first byte of response data from the server.
Technical Explanation & Importance
High TTFB (>600ms) indicates slow server hardware, un-cached database queries, or inefficient PHP rendering. Wefik themes and plugins optimize TTFB to under 100ms through static caching and lean database structures.
Key Engineering Takeaway
Understanding Time to First Byte (TTFB) is critical for engineering production-grade, bloat-free websites. All Wefik themes, plugins, and templates implement these standards natively.
