At least you have one user: it's me. Parallel builds saves ~20% time on
uniprocessor system and much more time on multi CPU one. I have access to
the dual Xeon system and have ~2x compilation speed up. It is real
improvement, thanks for your work!

Using -pipe option helps to save even more time (~5--15%, depending from
system type). Of course, this is only important for those, who need
recompile the whole library very often...
