HAMMER saw its first light of day in the July 2008 2.0 release. This filesystem has been designed to solve numerous issues and to add many new capabilities to DragonFly, such as fine-grained history retention (snapshots), instant crash recovery, and near real-time mirroring. The Hammer filesystem is also intended to serve as a basis for the clustering and other work that makes up the second phase of the project. -Recently, many developers have focused on SMP scalability while others have put an emphasis on new feature development and driver porting. The VM system was finally fine-grain locked all the way down to the pmap in late 2011, resulting in huge performance gains on many-cores machines. Further and more up to date information on the project goals and status are available on this website, and discussion of the project is possible on a variety of newsgroups, mailing lists and IRC. +From 2009 onward many developers have focused on SMP scalability while others have put an emphasis on new feature development and driver porting.

Major subsystems were scaled one after another. -DragonFly BSD was originally forked from FreeBSD 4.8 in June of 2003, by Matthew Dillon. The project is "the logical continuation of the FreeBSD 4.x series", as quoted in [Matthew Dillon's announcement](http://lists.freebsd.org/pipermail/freebsd-current/2003-July/006889.html). +In 2012 Francois Tigeot and a dedicated group of helpers began retooling drm (the graphics subsystem) with an active port from linux, slowly bringing the system up to modern standards. As of 2015 fully accelerated 2D, 3D, and video support is operational with Xorg. At around the same time there was also a concerted effort to upgrade the sound system with a major HDAA port from FreeBSD. Graphics, Video, and Sound have turned DragonFly into quite a nice desktop. + +In 2013 the PID, PGRP, and SESSION subsystems were SMP-scaled. In 2014 one of the few remaining SMP critical scaleability paths, the fork/exec/exit/wait sequence, including related page-faulting and library mapping, was fully scaled, greatly boosting bulk build performance and concurrency. + +Also during this period the network stack underwent a continuous stream of small SMP improvements to the point where today all major protocols, including both ipfw and PF, are fully concurrent with few locking collisions. DragonFlyBSD enjoys phenominal networking performance today. + +Further and more up to date information on the project goals and status are available on this website, and discussion of the project is possible on a variety of newsgroups, mailing lists and IRC. + +DragonFly BSD was originally forked from FreeBSD 4.8 in June of 2003, by Matthew Dillon. The project was originally billed as "the logical continuation of the FreeBSD 4.x series", as quoted in [Matthew Dillon's announcement](http://lists.freebsd.org/pipermail/freebsd-current/2003-July/006889.html), but this description has long since become obsolete. From a performance perspective DragonFly's only real competitor these days is linux. See all past DragonFly [[releases]].
