The FreeBSD response was to make the kernel more SMP friendly with finer-grained locking, and to bring-in the ULE scheduler. Dragonfly BSD was a fork off 4.x by people who thought a more radical kernel rewrite was needed. Their kernel avoids a lot of the locking problems by using message queues.
Just to clarify, that was the theory and intention behind Dragonfly, but in practise they have yet to achieve it after 4 years and any benefits of their ideas remain unproven. Basically they have achieved no performance gains on SMP and have effectively abandoned working on it.
