Hello, I have been testing Jython and I made some
comparissons with JPython.
The tests included the concurrent execution of large
scripts that perform parsing of big xml documents,
include some XPath querys, etc.
The results i obtained show that jython has a much
better memory usage than jpython but most of the tests
showed worse performance too (even 2 or 3 times in
some cases). May it be true? or perhaps i'm doing
Thank you very much and sorry for my english.

I think it would help if you could describe what you were doing, then
someone might be able to tell if you if it was wrong or not.
Some answers which might help
1. Which XML parser did you use?
2. Which XML memory model (DOM) did you use?
3. Which XPath processor did you use?
4. What was the size of the XML file you worked on?
5. Did you use the exact same versions of all of the above on both
Jython and JPython?
6. When you say "concurrent execution", what do you mean? How
reproducible are your timings if you are running several tasks at once?
