Some of this is Java's fault; some of this is ours. Profiling it, all I could see was a lot of time attributed to calling through PyReflectedFunction. In a quick test, subprocess.Popen in Jython took 28 seconds to spawn 1000 processes, using ProcessBuilder from Jython took 22 and using ProcessBuilder from Java took 12. subprocess from CPython took 3.
