Below is a script used by PythonXY for opimazation.
Maybe of interest for GRASS, too.

I do not have any further experience with optimazation on windows.
But it happens also on linux that the dialogs take time to pop-up.

For instance calling g.region on CML.

I guess there is happening something inside the wrapper...

(2x1.8Ghz, RAM> 2MB).

BTW, taking about the perfomance of a program shows that the 
design has reached a 
fairly stable state... These are minor improvements.
First, we need to be happy to have it.

Regards,
Timmie
