Our default setup gives you a slow build for a few reasons: optimisation is set
high, compiling via C is the default, GHC itself has to be built twice, and we
ship a lot of extra libraries.
However, many of these things can be tweaked, and it has been reported that you
can get a GHC build down to under 8 minutes on a dual-core, if you're prepared
to sacrifice optimisation and extra libraries. However, you can speed up the
build a *lot* just by using the native code generator instead of compiling via
C: gcc has been getting quite a bit slower recently.
Full details on how to tweak the GHC build are here:
