I'd be curious how it would perform on C# (windows/.net vs. linux/mono) .. though the environment setup would probably be a bit more involved.. and IIS is a very different beast.

I'd think that it would probably land somewhere close to Java Servlets, but a bit slower. The framework stack for web requests in .Net is probably a bit more than it is in the servlet server in question. I would also think that Mono would be a bit slower than IIS, only because IIS does very well at pooling resources/threads for multiple requests.

There's also the question of async .Net handling vs. blocking. Most .Net code I've seen is blocking, but there are async options, and as of the 4.x releases are much easier to use.

Thanks for the link, errnoh. You're precisely right, we want to have C# and .Net tests included but didn't find the time to do so ourselves in the past week and have not yet received a pull request. I was not familiar with ServiceStack prior to feedback we received to last week's test, but from the looks of it, I'd personally like to see how it does.
