Conventional optimization wisdom applies: find out where the bottleneck is, then put your effort there. In this case, I'd be surprised if ant is the bottleneck, rather than the compilation process. On the other hand, the bottleneck is, remarkably often, not where you'd think it was. Measurement is the only way to be sure.

I'm actually not compiling anything with ant during the development phase. My EJB classes contain xdoclet tags which are then used to create the interfaces for my beans and the deployment descriptors for JBoss. Ant/xdoclet just takes a long time to chug through the sources and generate the necessary files. It seems to me that a native application to do this should be quite a bite faster. I'm seeing anywhere from 40 seconds to 1.5 minutes depending upon how many classes have changed since the last run. A not insignificant part of that is probably just the JVM starting up.
Thanks,
