[wxpython-users] Profiling of wxApp shows XRC a real hog

[Frank Aune]

Hi,

I've been toying with the hotshot profiler lately, and looking at the 3 most 
expensive calls in my wxApp, reveals that XRC is a real resource hog:

 20802 function calls (20567 primitive calls) in 9.110 CPU seconds

   Ordered by: internal time, call count
   List reduced from 851 to 40 due to restriction <40>

   ncalls  tottime  percall  cumtime  percall filename:lineno(function)
        3    5.709    1.903    5.745    1.915 xrc.py:75(__init__)
        7    0.779    0.111    0.779    0.111 xrc.py:139(LoadPanel)
        4    0.198    0.050    0.198    0.050 _gdi.py:6097(GetFont)
      23    0.191    0.008    0.191    0.008 _gdi.py:515(__init__)
    209    0.085    0.000    0.086    0.000 _controls.py:4519(SetStringItem)
        2    0.079    0.039    0.079    0.040 _core.py:8841(Show)

As you can see, the startup was over 9 seconds (!) - normally it only takes 
3-4, but occationally it takes as long as the profile above indicates. I 
don't want to drop using XRC, as I like wysiwyg for GUI editing. But is there 
anything I could try to increase the performance?

Can I for example generate pure python code from XRC, without relying on the 
xml?
