yes, certainly, I'm aware of "make -j 3", but two separate projects which look at different files and parts of the disk (causing lots of head skips, cache threshing etc)?
It just sounds wierd to me that someone will run two such large compilations in parallel and then say that the compiler is slow. Slow compared to what? gcc in the same situation?
