By default, it appears most of the time during the build/compile process, only 1 single CPU core is busy, signaling missing of parallel compiling. Is there any best known practice to make it faster?

Now that I think about it, there is yet another not obvious "trick" that I should have probably mentioned:

You should definitively be translating PyPy with PyPy itself (rather than CPython); even though it will still use only 1 core, the translation will greatly benefit from the JIT. It's been a very long while since I've last checked, but I wouldn't be surprised about a factor 2x speedup or so...
