I assume below, that you run linux, or atleast use gnu toolchain. If
it is not case, I really don't know how to help you. Maybe someone
else knows.

To compile faster, you might try setting up ccache (http://ccache.samba.org/).
Also adding -jN argument to 'make' command might help, where N usually
is number of your processor cores +1, like -j3 for dual core. Hmm,
maybe Qt-creator could do something like this out of box? About
startup time of your code, well...
maybe checkout http://en.wikipedia.org/wiki/Prelinking, I never tried
that for development though. For debugging you could use striped from
debugging symbols versions of some libraries (those you know you don't
really need/want to debug). Please check 'man strip' for more info.
