[IMG=1]DragonFly, a distribution that belongs to the same class of operating systems as other BSD-derived systems and UNIX, is now at version 3.2.
The most important change in this latest version is about the scheduler, which received a major performance improvement, using postgres benchmarking as a measure.
Also, SB4BSD has been incorporated into this release, which means that more USB devices are compatible with DragonFly, and xhci (USB 3.0) users may be able to take full advantage of their newer hardware.
DragonFly 3.2 comes with a few noteworthy installation and upgrade notes. First of all, GUI disk installs and installations using HAMMER should be to disks over 50G in size.
Secondly, the installer can encrypt the root volume and the swap volume, but it will not work properly for other volumes despite any additional check-boxes. Installer and boot-time support works but is still a bit rough around the edges.Highlights of DragonFly 3.2:
• Several arbitrary bounds on kernel caches (such as the buffer cache) for x86-64 have been removed;
• Improved control over BREAK_TO_DEBUGGER by adding run-time sysctls, has been implemented;
• Sio console baud switching has been removed when console & getty/login is running on the same serial port;
• Size cap for tmpfs has been removed. This issue created problems in the past when mounting tmpfs partitions from fstab prior to swap being turned on;
• Numerous buffer cache clustering performance improvements have been implemented;
• A new filesystem independent quota subsystem has been added;
• Floating point rounding for long double in x86_64 platform has been fixed;
• Several Google Summer of Code projects have been added for PUFFS support, scheduler changes;
• The tmpfs filesystems can be exported over NFS;
• Several SACK related bugs have been fixed.
