[Mono-list] Mono C# versus Java 6 -server performance

[Jeffrey Stedfast]

I could be completely wrong, but my thinking is that the slowness is is
the Mono implementations of various things (VM, classes, etc).

There has been significant performance improvements done since 1.2.3, so
you might try that and see how things have changed (Mono still may be
slower than java6).
