Description: Time to First Byte (TTFB) is a crucial metric in web performance optimization that measures the time taken from when a browser makes a request to a server until it receives the first byte of data in response. This indicator is fundamental for assessing how quickly a server can start sending information to the client. A low TTFB is desirable as it suggests that the server is responding quickly to requests, contributing to a better user experience. TTFB encompasses several components: network time, server processing time, and queue wait time, meaning it can be affected by network latency, server load, and backend code efficiency. In a world where page load speed is a key factor for user retention and SEO, optimizing TTFB has become a priority for developers and system administrators. Tools like Google PageSpeed Insights and GTmetrix allow users to measure and analyze TTFB, providing recommendations for improving overall website performance.
