May be, I should file a > bug or feuture request ? FWIW, I agree that knowing the number of requests per from-client connection is useful. If this is not shown anywhere, a bug report or a feature request might help, and a quality patch adding those stats would be welcomed. mgr:pconn would be the right place to show those stats for all Squid sides that use persistent connections (whether pooled by Squid itself or by the clients talking to Squid). Reporting request concurrency level (i.e., the used pipeline depth) when pipelining with clients is enabled would also be useful. Thank you, Alex.
