you said "run time binding to signals".

so there is some evidence that GNOME might be slow. we also know
already that mozilla apps are large and heavy, and that they don't
even use GTK directly. this has very little to do with GTK.
>What can I do to improve it?
no idea, but the examples you gave are a long way from suggesting
that there is something deeply wrong with the basic "runtime" design
of GTK. the gnome-terminal is not one of the faster terminal emulators
anyway, and thats not because it uses GTK, but because of other
aspects of its design. registering apps on startup with "The GNOME
Desktop" is definitely slow, and can lead to lagginess in application
startup. But for a fair comparison, try the GIMP - a big badass
program written in 100% GTK: it shows almost immediately *and then*
appears slow as it churns through its non-GTK-related initialization
