100% echoed. I have never seen GTK+ as "slow", and in fact my
machines, which are dominated by GTK applications, always seem faster
to me than Windows systems (even with faster hardware), and marginally
snappier than some Qt/KDE apps running on the same hardware.

Before you make such vast and overwhelming suggestions ("runtime ->
compile time binding" is very, very far from a trivial change
in the entire design of GTK), please come up with some hard
numbers. Nothing could possibly justify the work required to make such
a change without a set of well-measured comparisons of similar
application code that show the GTK implementation to be fundamentally
slowed by signal marshalling. 

And speaking personally, I don't believe that any measurements you
could make will show such a thing, but I'm willing to keep an open
mind.
