[wxPython-users] wxPython memory usage

[Dreas van Donselaar]

Hi Andrea,

Thanks for your quick response. The VM Size is indeed not affected by 
closing/minimizing. It shows 40MB though which seems to be quite a lot. 
I guess we have to optimize our code somehow. Or are there "general 
tricks" to lower this? Is 40MB common for a Python/wxPython app?

Kind regards,

Dreas van Donselaar
