FreeBSD’s SMPng OpenBSD 3.6 Live


Over the past five years, the FreeBSD developer team has worked very hard to improve performance on multiprocessor systems. Their goal was to remove the big kernel lock used in the 4.x branch, and replace it with fine-grained SMP support. This project, often referred to as SMPng (“SMP next generation”), was a very big effort and took four releases (from 5.0 to 5.3) to reach stable status.
