Hi Peter,
Thanks for the update. I'm really happy to see PyXB on Python 3.x. I've
just tested it using some XML documents here and noticed a slight
performance reduction in using 1.2.3-DEV on Python 3.3.2 vs 1.2.2 on Python
2.7.5. The test I ran was marshaling and unmarshaling 96 XML documents,
ranging from 150 bytes to 58kb in size (so, pretty small). The XML schema
is around 4000 lines long, so non-trivial.
On Python 2.7, pyxbgen took 3.145 seconds to run, my tests took 5.007
seconds to run.
On Python 3.3, pyxbgen took 3.626 seconds to run, my tests took 5.871
seconds to run.
So at first glance I'd say the Python 3.x build looks to be 10-20% slower
than the Python 2.x build. But functionally it looks pretty good so far.
Thanks again for your efforts. We'll start using this internally and we'll
let you know of any issues we come across.
Regards,
Nathan.
