You want orders-of-magnitude performance increases.  Changing languages 
won't give you that.  Some suggestions:

1) make sure you're using the most efficient algorithm

2) make it run distributed on multiple machines, like seti@home

3) if you have a lot of machines of a particular type (p4 for instance) 
then you might consider optimizing the critical path with assembly code, 
SSE instructions, etc.

4) if that still doesn't do it, consider dedicated FPGAs
