[ardour-dev] On performance issues with GTK

[Carl Seleborg]

Hi all,

This question is not specifically Ardour-oriented, so I apologize if 
it's too off-topic. I just thought I'd ask here, since I know some of 
you have become experts in the field by now.

What's the performance risk when using multiple windows in a GTK-based 
application (gtkmm, actually) running real-time audio? I mean, is there 
a long interrupt when the user switches from one window to another? Is 
there a good reason to keep the number of windows down to a minimum? 
What if all GUI handling is done in a separate thread? Are there things 
to avoid doing in a GUI when doing real-time audio?

Thanks in advance to those who can provide me with some info on the 
topic. And thanks to the rest of you who actively contribute to Ardour.

Cheers.

Carl
