Well, there is the just in time compiler (JIT) that compiles classes when
they are loaded (or something similar). There is a to-native code compiler
on the PC, but I forget the name. I tried my app out on it and it didn't
really run any faster. From what I know about Java most of the speed hit
comes from either API shenanigans (slow API implementation), the GC, object
allocation, overhead for things like every object having a monitor and the
most natural way of doing things in java tends to also be slower than the
most natural way of doing things in C. It's a knockout combo of overhead.
