That's a great tip, :-). Just done with an experiment, and PyPy2 5.4.1-alpha0 cut down build time by 27% compared with CPython2.7.6 Thanks!

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... -- Sincerely yours, Yury V.
