I see that may be the case.
My program uses a lot of File IO and it is divided into multiple processess , working good in python.Failing so far in pypy (due to requirement of so many different document parsers) .
I tested with Jython and i frustrated (At-least , in jython i can use Tika to parse documents) .

If your problem is hard to divide in multiple processes but easy to
divide in multiple threads, and if you have a machine with enough
CPUs, then Jython wins.  Although dividing in multiple raw threads is
rarely easy.
