TTFB (Time to First Byte) measures how long a browser waits before receiving the first byte of data from a server after making a request. It can be influenced by DNS lookup time, network latency, server processing, caching, and hosting performance. A lower TTFB generally means the server begins responding more quickly, helping create a faster browsing experience. Monitoring this metric can reveal important performance bottlenecks.
