Not all the mono codepaths have been optimized yet, so
in some cases we may be significantly slower than the MS runtime.
A few of the cases we are aware of and we have plans to improve 
the performance. If you want us to take a look at the slowdown
you see you should submit a small sample application that does
the same things your app does and demostrates the issue, so
we can see why it's slow and fix it. Until then we can't do much
for your particular issue.
