[Mono-aspnet-list] Weird slowness problem with fastcgi-server4

I have a ratther big MVC4 application that runs without problems under Mono
3.2.3.  Recently I found out about a weird behaviour.  My page controllers
(in particular a Model Binder) take a very long time - about 5 seconds - to
access the parameters in the HttpContext.Current.Request object. Other than
this, the application behaves normally.

I found the culprit in the "master" tag of xspon GitHub, I switched to
3.0.11 and the problem was (apparently) solved, each access requires only a
few milliseconds, as it should be normal. Unfortunately I use XSP4 for
testing only, so when I switched back to fastcgi-server4+nginx, I still had
the same problem.

Was some fix backported to fastcgi-server4 and not xsp or should I look for
something else? fastcgi-server4 and nginx currently communicate via TCP,
I'm going to switch to Unix sockets and re-test but I don't know if it will
really make a difference.
