I tested on two laptops (Ubuntu and Mac OSX). I compiled the two

touching all .go and all .d files involved. Then I divided the
compilation times by the line counts of *.go/*.d files as wc has them
and compared the results.
On OSX dmd was 4.3 times faster. On Ubuntu, the ratio was 4.45.
Was D with or without --unittest? I'm asking because unittests are instances
and plenty of Phobos is templates for which AFAIK much work
is deferred to instantiation.
No -unittest. In Phobos the unittest build turns -unittest on separately
for each module, so I can't quickly test the build speed with -unittest
on. That being said, there's still plenty of non-template code in Phobos.
BTW Phobos is built in release mode (as I assume go's library is).
Building in debug mode reduces build time by more than a third.
