Leverage Dual CPU's with GNU Make
Authored by: ceesaxp on May 04, '04 01:33:07PM

Very comprehensive, but I'd still add that it may all also depend on (a) version of make in use; (b) OS in use; (c) what is being compiled.

On my FreeBSD machine, buildworld/buildkernel runs with -j10 (it is a dual Celery 466). Can't say it is x10 viz. no -j flag, but it is pretty fast. However, I never compile any ports with -j flag, as sources are really tailored well for parallel make. Pitty, since I would not mind recompile of KDE to take even 50% less than current c.a. 10 hours...
