My experience is that debug mode makes a huge difference in performance. 
Have you made sure that all object files (src/Object/*.o) were deleted 
before recompiling without debug mode? The make mechanism will use the 
existing *.o files even if the compiler flags were changed.

PS: I have a completely reworked event-loop for Qt-TeXmacs finished and 
running. It solves a number of problems. I'll submit it as soon as I am 
confident that it fixes more bugs than it creates...
