Server Side Performance

Use HTTP response header Server-Timing.

Server-Timing: setup;dur=2.4

Server-Timing: prelude;dur=53, dbconnect;dur=47.2

Use Nginx Measure Response Time

• $request_time = timeresponselastbyte - timerequestfirstbyte
• $upstream_connect_time
• $upstream_header_time
• $upstream_response_time

And use response header field.
