[pypy-dev] Why is pypy slower?

[René Dudfield]

Hi,

you can run it as a daemon/server(for example a little flask app). This
optimization also works for cpython apps if you want to avoid the
startup/import time.

Can the work be split up per xml file easily? Then perhaps multiprocessing
will work nicely for you.

Do you need to process all the files each time? Or can you avoid work?

cheers,
