Pushing FreeBSD's SMP performance
Author: JT Smith
BSDToday has a brief piece discussing the SMP system in FreeBSD 3.x and 4.0, and how it will change in the future to accommodate better SMP expandibility. This change will remove a global kernel lock which stops SMP performance from increasing much past 2 CPUs, and improve the code by allowing the kernel to have different threads to handle interrupts.
