Ben, Thanks for the tip. Performance is very important for the code i am writing but thought that a OO programming platform would ease the development a little bit. Oh well. Guess i do have to do it in C or Fortran.
I imagined that .NET 2.0 would bring in lots of performance improvements in the framework or that's what i remember reading in one of the blogs at MSDN. But like you said, a procedural language will definitely be faster than any of the OOP languages, anytime ! Thanks for all the help guys.
