Whitelisted ports will automatically make use of all processors available in your computer." Most large ports I have seen (and use) luckily take advantage of all available processors during build (which completely sucks for desktop systems, but then, you normally shouldn't do that on a station where you try to work, so I'm fine with that). There's no way you'd be able to build 450 ports in 45 minutes if you were using only one CPU/core. > It has happened: > > http://lists.freebsd.org/pipermail/freebsd-ports/2009-March/053736.html > > I believe *dependencies* of a port will be compiled using one process (and > thus CPU) at a time, however. > Interesting, are you sure this really happens? At least I understand you mean that - let's say - when i choose to compile, i.e. www/webkit directly, it will use all available processors (which it does, all the time), but when I try to compile, say, www/epiphany, which pulls www/webkit as a dependency, it will get built without MAKE_JOBS_SAFE, locked to a single processor? I can test in a short while if that's really the way, just asking, if I got you right.. m. _______________________________________________ freebsd-ports(a)freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-ports To unsubscribe, send any mail to "freebsd-ports-unsubscribe(a)freebsd.org"

No. Only one port is built at a time but if that port is MAKE_JOBS_SAFE it will build in parallel. -- WXS _______________________________________________ freebsd-ports(a)freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-ports To unsubscribe, send any mail to "freebsd-ports-unsubscribe(a)freebsd.org"
