This should give a nice boost in the already awesome job FreeBSD's developers have done profiling the kernel in the 7.x and 8 branches.

Note that DTrace on FreeBSD can only be used for kernel-space probing, for the time being. Userland probing is expected in a future release.

Interesting news. I really liked FreeBSD in the past, but rather lost sight of it in the last few years, primarily because of the excellence of Debian and Ubuntu. This is my excuse to give it another go as a server OS. :)

IMHO FreeBSD is really starting to shine. I've been using it solidly since 5.x where is was stable but slow and I've deployed 7.0 many times and I quite frankly love it to death.

The BSD's don't have the fan boys that linux has but FreeBSD really is an excellent and highly organized unix variant.

Possibly a stupid question, but what does "guernsey" mean in this context? Other than the island I've not encountered the term.

Ah, ok, seems to mean "Wins approval" http://www.willyourememberme.com/australia/austslang.html

In northeastern CT, it means a type of cow[1], which made the headline humorous.

Mildly funny story: my grandma once said at a family gathering, telling a story of somebody in the hospital, "then they wheeled him off on a guernsey", which everyone thought was pretty hilarious.
