[Mono-dev] Mono runtime performance

[Gary Smithrud]

I would suggest build the Mono version with optimizations on and  
seeing the performance differences as well.  Of course this is not a  
total surprise, since Mono is newer than .NET and as such the goal  
should be first to get it right and then to speed it up.
