How slow is it? Is it the program, or Java that is slow?
Reasonable Java code is supposed to run, with JIT enabled, about as fast as
C tends to be a little faster, as there is overhead in memory
allocation/deallocation for OO programming, independent of the language.
I would look at gcj and see if that helps any. Otherwise, your algorithm
may be less efficient than it could be, or it might be using Java
