It is safer and runs just as fast. : : Dunno if it was a temporary compile problem, but I've actually found that: : : make -j 3 buildkernel : : hasn't worked properly for me. Either it was a temporary thing and may be : fixed now, or it's a property of the buildkernel dependencies, and should : probably be fixed (my kernel build is substantially faster with just a bit : of parallelism to keep the CPU busy). I think that it works. I know that the "old way" works with -j values up to 20 (haven't tried anything higher). There were issues with -j for a while, but those have been fixed. They were inadvertantly introduced when we went to building modules. Warner To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
