DragonflyBSD 3.0 was released today with major performance improvements for multi-core systems thanks to the recent VM SMP work, plus file-system performance improvements for HAMMER, and many other changes.

Back in October I wrote about huge SMP performance improvements for DragonflyBSD thanks to VM SMP changes. This work has landed in DragonflyBSD 3.0. The SMP kernel has now become the default in DragonflyBSD over the uni-processor kernel. "Previously the majority of the VM was under a single token, the vm_token; now vm_objects (mappable entities) are each under a private token, concurrent page faults in the same object can proceed, and VM SMP scalability overall is improved. Results for Postgres and MySQL, among others, are excellent."

DragonflyBSD's HAMMER file-system has also seen major performance improvements due to a new time domain multi-plexing method. Earlier HAMMER file-system benchmarks can be found in this article.

Another disk improvement for DragonflyBSD 3.0 is tcplay, which provides TrueCrypt-compatible disk encryption.

Full details on DragonflyBSD 3.0 plus download links to the various flavors can be found from the DragonflyBSD web-site.

Phoronix benchmarks of DragonflyBSD 3.0 are forthcoming.
