I'm trying to understand more about the Haproxy timings. Below is a snippet of the timings from the Haproxy manual:
Tq: total time to get the client request (HTTP mode only)…
Tw: total time spent in the queues waiting for a connection slot…
Tc: total time to establish the TCP connection to the server….
Tr: server response time (HTTP mode only)…
Tt: total session duration time, between the moment the proxy accepted it
and the moment both ends were closed…
Source: http://cbonte.github.io/haproxy-dconv/configuration-1.5.html#8.4
I've attempted to diagram some of the timings, but my diagram is probably incorrect and is definitely incomplete (no FIN, etc):
Question: What would the full timing diagram look like, including all timing measures (Tq, Tw, Tc, Tr, Tt) as well as all TCP/IP communications?

Nice picture :)
