Run the java app as a server. I did this with javac, and went from 5000ms (ant) to 200ms (averages). It gets faster each time it runs, enormous speedup after the first run; but still very significant for the next 10; and continuing at a slower rate from then on. The client needs to be non-java, to avoid the startup cost there. I run it as a console, so that is the "client" (wrapped in rlwrap, for filename completion/editing etc). My workflow is to compile in a separate shell; that's why I did it this way.
