DragonFly BSD
DragonFly BSD Description
- DragonFly is an open source BSD operating system designed to be the logical continuation of the FreeBSD-4.x OS series. It is very similar to other BSD-based distributions, such as FreeBSD, NetBSD or OpenBSD.It is a fork in the path, so to speak, giving the BSD base an opportunity to grow in an entirely new direction from the one taken in the FreeBSD-5 series. On top of that, it includes an unique set of features that differentiate it from other similar OSes.HAMMER is DragonFly’s main attraction, a modern, high performance filesystem that features historic access functionality and built-in mirroring. The kernel is also one of the reasons why DragonFly is a better BSD distribution.DragonFly’s kernel includes two different schedulers, one that schedules all executable entities (Light Weight Kernel Thread) and another one that selects a single user thread at a time for each processor and abstracts out user threads (User Thread Scheduler).Additionally, the kernel features a complex kernel memory allocator comprised of an object-oriented memory allocator and a basic kernel malloc called kmalloc(), the DragonFly device filesystem (DEVFS), a virtual kernel (VKERNEL), NFS V3 RPC asynchronization, and a disk I/O scheduler framework (dsched).Among other interesting features, we can mention the NULL Filesystem Layer (NULLFS ) that supports non-looping arbitrary mount points, TMPFS (Temporary Filesystem VFS), transparent disk encryption, managed SSD (Solid Storage Device) support, variant (context-sensitive) symlinks, DNTPD (DragonFly Network Time Daemon) and DMA (DragonFly Mail Agent).In addition, users will be able to checkpoint or suspend processes to disk at any time. The distro provides strong AHCI drivers, stable device names, as well as well grounded encryption and volume management.Overall, DragonFly proves to be a modern, user-friendly and very accessible UNIX-like operating system. It can be used on a daily basis as a desktop system or as a powerful BSD server.

See the PDF of graphed results to see the improvements. DragonFly should be now one of the best selections for Postgres and other databases. New USB stack: · USB4BSD has been incorporated into this release. More USB devices are compatible with DragonFly, and xhci (USB 3.0) users may be able to take full advantage of their newer hardware. Since this is a new feature, it is available in 3.2 but not built by default. See the original announcement for how to do so. �.You can free download DragonFly BSD from Softpedia now.
