[MonoDevelop] MonoDevelop OSX / Windows performance differences

[Stifu]

That doesn't match what I've read or seen myself.
The only thing that I found was significantly faster in Mono than in .NET
was exception handling (which might be partly due to the fact Mono doesn't
do as much as .NET, but I digress). Which doesn't matter too much, as
exceptions are supposed to be exceptional.

In most cases, I get similar performances and memory usages. Except for
certain intensive operations, Windows technologies (WinForms, GDI+), or
certain classes (DataSet, DataTable, etc...) where .NET is often clearly
faster. Add to that Mono's GC (although it is being replaced), which
sometimes performs much worse than the one of .NET.

Anyway, back on topic, it's good to see you found the solution to your
problem, Philippe.
It would be interesting to see how these numbers compare to what you get on
Windows.
