> On a slow machine I sometimes use to build Derby, running the org.apache.derbyBuild.splitmessages tool takes 30 seconds and accounts for 15% of the total time needed to run "ant -q buildsource" (which builds the engine, the network server and the client, but not the tests or demos). The tool is invoked 15 times, and each time a new Java process is started because the Ant target has specified fork="yes". By changing it to run the splitmessages tool in the same Java process as the one running Ant, the time is reduced to 3-4 seconds on the same machine.
