I did a buildworld/buildkernel last week with "-j 8" on my dual celeron system and all, apparently, went fine. It saved about 30-40% of time. Version 4.2-stable. Could someone, please, explain to me why the "-j" stuff could be dangerous ? It's not much clear to me why doing more then one "cc" (example) at time could break the final object code. (no flame, it's a very honest question! :-) ) TIA a lot! :) > 4-8 is good for a single processor with enough ram (gcc is large), > 4-24 is ok for a SMP box. I did with 8 and now trying with 10 (I've only 96Mb RAM) -- bye! Ale aledema@iol.it To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
