Sounds like you can benefit both from faster compiler and from faster

Perhaps, but 28 seconds isn't really that bad. Particularly compared
with the systems I used forty years ago :-)
 

It is pretty bad. Breaks flow of thought.

BTW, can you experiment with -O0 ? What speedup does it provide over

We typically use -O3, except on a couple of source files which
take over 6 minutes of CPU time to compile, each, when -O3 is
specified.

For project of that size, I'd say that there is 80% chance that result
of compilation with -O3 is slower than -O2.
