I know many instences which eventually show that python is faster.

Compare eclipse and glade.  I am not a hard core hacker on compiles or
interpriters but as an end-user, I see almost all java programs r pritty
heavy on memory and python is pritty fast and zippy.

I for example use a screen reader called orca, because I am totally

Guess what, the screen reader moniters every event that happens in the
OS (gnu) and also extracts all the information of every widget and keeps
track of the location of the focus and many more things and also
constantly streems output to a speech synthesizer as it take the
information from the desktop.

All this should happen at run-time without any latency.  This software
is in python and it delivers what it is supposed to at great speed.

Further, I have an accounting software which was previously in java, but
now in python and the performance gain is ausom.

Yes it depends on how we write the code but comparing the 2 at least at
the middle layer and front-end (pygtk) python is faster than java.
Infact I am most certain that swing is not even 50% as fast as pygtk or

These are my personal observations and should not be taken as

happy hacking.
