This is going on the thinking that Linux uses a subsystem lock that allows all the CPUs to work on their own parts of the kernel simultaneously--theoretically eliminating processor idle time--whereas FreeBSD's spin lock allows only single CPU access at any given moment. Did we get this right? We don't have SMP hardware to test this idea. (Let me know if I should take this to smp or hackers instead.) -- dpilgrim@uswest.net /\ / __ Our lies are merely the gryph@mindless.com / \/OC/URNE truth of another world ICQ: 29880099 Death is not a kill -9, just a DALnet: anim0s make world and shutdown -r now PGPKey availble To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-chat" in the body of the message
