No, this is not a known problem, and in fact, little performance testing 
has been done so far on MinGW GCC specifically.

Yes, it would help if you could give us an idea of what part of the code 
specifically causes this problem.

It would also be helpful if we knew what optimization flags you are 
using, and what effect options like -ffast-math had on this speed 
difference.
