According to my impression, I feel that FreeBSD has moved away | from the single "GIANT" SMP lock, and uses separate locks for subsystems | like the ISR routines, spl system, etc. This should get preformance | improvements compared to Linux 2.2, which used a single kernel lock, | effectively permitting only one thread (or process) to be in the kernel | at the same time. | | Please correct me if I am wrong, and preferably provide some pointer to | documents pertaining to the same. /usr/src, CVSweb, and -SMP archives. :) -- +------------------------------------------------------------------+ | keichii@peorth.iteration.net | keichii@bsdconspiracy.net | | http://peorth.iteration.net/~keichii | Yes, BSD is a conspiracy. | +------------------------------------------------------------------+ To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-smp" in the body of the message
