[ardour-dev] On performance issues with GTK

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.
