Big-ticket items

swapcache - This is a mechanism which allows an attached solid state drive to be used to cache data and/or meta-data for other filesystems. The meta-data caching feature is particularly useful for machines which manage millions of files. About 2 million inodes and their related blockmaps can be cached per gigabyte of SSD. DragonFly supports up to 32GB of swap, per swap device (up to four) on i386, and up to 512GB of swap, per swap device, on 64-bit, so a very large number of inodes can be cached. Please see the swapcache( 8 ) manual page for more information.

HAMMER - Our filesystem now supports a REDO log on top of the UNDO log it already had. The filesystem will use the REDO log forward-log write and file-extend operations which allows fsync to accomplish its goals with only REDO log writes. This greatly improves the speed of fsync without weakening HAMMER's fast-recovery feature.

tmpfs - The tmpfs port we did from NetBSD is able to fully utilize the VM page cache on the system as well as swap space, with no duplication of data (unlike MFS) and very good cache characteristics which reduce or eliminate disk activity under nominal operation.

Big-ticket items

Hardware and multiprocessor support - This release supports a much larger variety of hardware and multiprocessor systems than previous releases, thanks to updates of ACPI and APIC and ACPI interrupt routing support.

Hammer Deduplication - Hammer volumes can now deduplicate volumes overnight in a batch process and during live operation. The 'hammer dedup-simulate' command can be used to estimate space savings for existing data.

Packet Filter (pf) - Pf was updated to a version based upon OpenBSD 4.4. The previous version of pf in DragonFly was based on OpenBSD 4.2.

Compiler updates - DragonFly now uses gcc 4.4 as the default system compiler, and is the first BSD to take that step.

New bridging functionality - The bridging system has been rewritten. Multiple interfaces on a single system can be bound together transparently under a single virtual MAC address, and bandwidth aggregated to that new interface.

MP Performance - The MPLOCK (the primary lock, that when held ensures only a single cpu is operating within the kernel) has been removed from every area except the VM system. DragonFly is one of the few non-academic operating systems to use a primary sychronization mechanism that is not a blocking mutex

Overall Performance - DragonFly now offers significant performance gains over previous releases, especially for machines using AHCI or implementing swapcache(Cool.

ACPI Support - Major update to DragonFly's ACPI support have been made, particularly for interrupt routing.

Pored toga jos i OpenBSD pf iz 4.4, kriptovanje root i swap particije prilikom instaliranja sistema, podrska do 63 procesora i ukupno 512 GB RAM-a na 64-bitnoj platformi, pkgsrc-2011Q1 paketi, GCC 4.4.5...

DraognFly BSD dolazi u formi .iso imidza za 32-bitne i 64-bitne platforme, kao butabilni usb imidz, ili butabilni usb imidz sa X okruzenjem.

DragonFly BSD 3.0.1

Citat:DragonFly 3.0.1 is now available! This release has superior multiprocessor support compared to previous versions. Speed has improved significantly. Big-ticket items: 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; a new time domain multiplexing method has been added to balance storage operation types over long time periods; ACPI + interrupt routing have been upgraded, an SMP kernel will work on all machines and is installed by default; DragonFly now has tcplay(Cool, a tool for creating and managing encrypted disk volumes.

DragonFly Release 3.2

Najsvezije izdanje DflyBSD sistema, dolazi sa USB stekom druge generacije (podrska za USB 3.0 izmedju ostalog), poboljsanja u scheduleru koja omogucavaju bolje iskoriscenje Intelove hyperthreading tehnilogije, kao i ponovo napisani delovi schedulera koji omogucavaju da PostgreSQL ima performanse slicne ili iste Linux kernelu, i bolje od svih ostalih BSD sistema (pogledati: http://lists.dragonflybsd.org/pipermail/users/2012-October/017536.html)
Citat:DragonFly Release 3.2

Big-ticket items

Performance improvements under database load
Significant work has gone into the scheduler to improve performance, using postgres benchmarking as a measure. 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.

Availability

Four release options are now available for 32-bit as well as for 64-bit. 64-bit installations are recommended if you do not need the linux emulation layer.

An ISO, to be burned to a physical CD or used as an image to install a virtual machine.
A bootable USB disk-key image. (minimum 2G USB stick needed)
A GUI bootable ISO image with a full X environment. DVD disc required.
A GUI bootable USB disk-key image with a full X environment. (minimum 4G USB stick needed)
The GUI images also include a snapshot of our git repos in /usr/src/.git and /usr/pkgsrc/.git which can be incrementally updated after the installation.


The release ISO images should be available on most of the mirrors. If the ISO is not available on a certain mirror, please try another one or download it from the DragonFly master site. Each image is in the "Live CD" format, meaning that it boots into a running and fully functional DragonFly system, which can be used for testing or system recovery tasks as well as installation. Check the hardware page or boot a Live CD to check for compatibility.

The GUI bootable USB image also contains the DragonFly git repo in /usr/src and the pkgsrc git repo in /usr/pkgsrc. The code can be trivially checked out using these repos and can be incrementally updated from master sites, post-install. See below for methods to obtain this code using the other images.

Neke stvari koje treba imati na umu prilikom instalacije"
Citat:...
DragonFly 3.2 Special Installation and Upgrade Notes

Disk size warning - GUI disk installs and installations using HAMMER should be to disks over 50G in size. HAMMER history will consume disk space quickly. Either use UFS on smaller disks, or prune your file history carefully.

Virtual PC users - Virtual PC does not supply serial numbers for the virtual disks. The system may need to be manually directed in the boot loader if the disk identifier changes. (Hit ? in the boot loader for a list of available volumes.)

Qemu users - If you see a large number of error messages on the console when booting, you may need to boot DragonFly with ACPI disabled. This can be done in the menu presented at initial boot. If that doesn't help, try placing hw.ioapic_enable=0 in /boot/loader.conf.

Installer Crypt Options - The installer can encrypt the root volume and the swap volume. It will not work properly for other volumes despite any additional check-boxes you might see. Installer and boot-time support works but is still a bit rough around the edges. Performance will be relatively high on multi-core machines.

DragonFly Release 3.4



Citat:Big-ticket items


Experimental packaging system: dports

John Marino has created a system, DPorts, that uses the FreeBSD ports system to build ports for DragonFly, and uses pkgng to manage the binary packages produced from those ports.

The default packaging system on DragonFly is pkgsrc. To use DPorts, you must remove or disable pkgsrc packages. Pkgsrc and DPorts cannot be used at the same time, or have packages mixed together. See the DPorts Howto page for details on installing and using DPorts. Note: this is the first release with DPorts, and this is still experimental.

The DragonFly snapshots are built using dports. (and also have XFCE for the desktop)

Performance improvements under extreme load

The process of testing poudriere, a tool for mass-producing binary dports packages, exposed stability issues when repeatedly mounting and unmounting many tmpfs systems on large multicore (48) systems. These issues have been fixed. In addition to stability, several changes were made to improve performance in situations with heavy processor and disk usage.

Improvements in poudriere performance, tmpfs performance, and CPU usage (graphs are linked in those message) were graphed by Francois Tigeot and posted on the kernel@dragonflybsd.org mailing list.

New default compiler

The two base compilers have swapped roles. GCC 4.7, introduced as an alternative compiler with Release 3.2, is now the primary compiler used to build DragonFly. GCC 4.4 remains on the system and still has an important role as the primary DPorts compiler. GCC 4.7 brings OpenMP (parallel programming) support to DragonFly via libgomp as well as stack smashing protection via libssp, neither of which was supported by GCC 4.4. The newer compiler also offers improved C++ and Objective-C support, and introduces Link-Time Optimization (LTO) support.

New USB stack

USB4BSD is available this release, though not by default. 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 3.4 but not built by default. See the original announcement for how to do so. This feature was available in DragonFly 3.2 but is still experimental.
