What affects time to first byte?
Posted: Mon Dec 23, 2024 3:56 am
The time to first byte, TTFB , is an indicator that measures the time from the client's HTTP request to the first byte returned by the server. As is easy to deduce, the lower the response time of a WordPress site, the faster and more responsive the server on which your web project is hosted. The TTFB is, therefore, a measurable value that can be obtained by evaluating some specific parameters.
The time to first byte value is influenced by three key actions: sending a afghanistan mobile number request from the client to the server, processing the request on the server and generating a response, and sending the response from the server to the client.
Sending a request to the server. TTFB measurement begins at the time of a request. The time it takes for a server to receive it can vary based on the time it takes to perform a DNS lookup, the speed of the user's network, the distance from the server, and any connection interruptions.
Response Processing and Generation. Once a server receives a request, it will then make a response. To reduce TTFB, many WordPress sites resort to page caching, server-side code optimization, and hardware resource optimization.
Sending the response to the client. When the server processes the response, it must transmit it to the user. The TTFB is determined when the client begins to receive the response, that is, when the first byte is delivered. The transmission time of a request and response can account for almost 40% of the TTFB value.
