Why "a lot"?  Let's say we compile only 10% of the distribution that
matters and that binaries account for about half of a package's
installed size.  That's an 0.5% increase in distribution size?

Because of the 10% size presumably?  They can't run more than 10%
slower.  And probably much less as NOPs take minimal time to execute.

few packages that are computation intensive.
