C# vs C - Big performance difference

Question

I\'m finding massive performance differences between similar code in C anc C#.

The C code is:

#include 
#include 
#inclu         


        

Answer 1

The other factor that may be an issue here is that the C compiler compiles to generic native code for the processor family you target, whereas the MSIL generated when you compiled the C# code is then JIT compiled to target the exact processor you have complete with any optimisations that may be possible. So the native code generated from the C# may be considerably faster than the C.
