Not really. Optimization takes what it takes. The question is whether
you do it badly, one file at a time, or globally, one binary at a
time. What gets longer if certain optimizations are turned on is the
compile/edit/debug cycle.

But what's interesting is that there is a middle position where most
of the heavy lifting is done by the front end, and the optimizations
performed in the linker are (from a time perspective) relatively

So from a developer perspective this may be more of a "tuning knob"
problem than anything else.
