Re: [orca-list] Misteries of low performance of Orca and distros

[Alex Midence <alex midence gmail com>]

This link is to the readme file for the NVDA source code.  If you will
note, one of the dependencies is the boost c++ library version 1.74.  Yes,
the primary language NVDA is written in is Python.  However, there are some
areas where "lightning fast" performance was a must that had to be written
in c++.

For the record, I was merely speculating on the effect of making a screen
reader using a compiled language over an interpreted one.  It was just a
guess.  This is the most discernible difference from my perspective with my
admittedly limited grasp of the underlying factors.   I'm sure there are
many other factors at play though.  

Regards,
Alex M

Hi,

And I might add that Python 3 seems to run faster than Python 2.7 and
earlier. As I indicated in my prior post I don't believe the problem is a
simple as a Python verses C++ issue as Alex indicated in his post.
