[Mono-dev] FastCGI Performance

[Marcelo Zabani]

  In case you want to host an OWIN application with Mono and FastCgi, you
may wanna take a look at a project of mine, Fos:
https://github.com/mzabani/Fos
It is also available at NuGet.

Someone looked into Mono FastCGI performance a couple months ago and made a
series of blog posts:

http://forcedtoadmin.blogspot.com/2013/11/servicestack-performance-in-mono-p2.html

He ended up writing a replacement for the Mono FastCGI server instead of
changing it because of architectural changes:
