Sun Java isn't really tailored to embedded systems, think of it this 
way, you're running a real CPU with a OS on top of it, then you're 
running a virtual cpu with your app on top of that.  Java will never be 
as fast as a C app, not unless you have a CPU capable of running Java 
bytecode natively.  Try JamVM or one of the other low-footprint Java VM's.
