I don't know that mono is guaranteed to be slower or not, but definitely a lot fewer man hours have gone into polishing mono as compared to the amount of effort spent to polish the .net framework on windows. Further, even if Mono itself is as fast as the .net framework, IIS the web server is going to be totally different performance characteristics from whatever webserver you are using on linux. I am glad you showed me the error of my ways because I would have guess .net was somewhat faster than mono, but it goes to show even more comparing across operating systems is meaningless... now i would love to get my hands on the numbers dont get me wrong, just saying if i was running the project I wouldnt go through the amount of effort required to get the .net results.
