#28835 — pyQT performance?

Anybody has the experience of the performance of the program developed by pyQT? Is it much slower than the one made by QT, such as (20%)?

For my experience, 20% is really surestimated.

I'm developping only with PyQt and essentially in the imaging domain
(viewing, transformation)
and I've never seen a difference of processing speed with the same
applications written in C++.

Qt + Python, a very good association.

Have you ever used py2exe? After converting the python codes to executable, does it save the time of interpreting the script language? Thank a lot!

Py2exe normally never speeds up anything, simply because it doesn't 
convert to executable, but simply
package everything together, so I haven't tried in this particular case 
but it shouldn't make a difference..
