TTFB and server response time monitoring
Server details splits the time before the first byte into DNS, connection, SSL and backend time, so you can tell whether a slow start comes from your server or the network.

Questions about Server details
What is a good TTFB?
0.8 seconds or less is considered good.
Is a slow TTFB always the backend?
No. DNS, connection setup and SSL can add hundreds of milliseconds before the server starts any work.
