Security oriented BSD operating system OpenBSD is making the move to disable Hyper Threading (HT) on Intel CPUs and more broadly moving to disable SMT (Simultaneous Multi Threading) on other CPUs too.

DragonFlyBSD 5.2.2 is now available as the latest stable release to this popular BSD operating system.

The newest weekly release candidate of the upcoming FreeBSD 11.2 is now available for testing.

Two weeks back we shared the news that one of Intel's open-source Linux graphics driver veterans decided to change roles and is now focused on improving FreeBSD for Intel hardware. Ben Widawsky is working on FreeBSD improvements that can at least relate to Intel and it turns out the company has a new team of developers on the task.

For FreeBSD 12.0-CURRENT in development there is now kernel support for pNFS while the user-space components are landing soon for this Parallel NFS support.

While the DragonFlyBSD kernel has already landed its mitigation for Spectre V1/V2 and Meltdown CPU vulnerabilities, a fresh round of CPU bug hardening work was just merged into their kernel.

The second release candidate of FreeBSD 11.2 is now available for testing.

Going back to when TrueOS was known as PC-BSD, the operating system has generally been known as a desktop-friendly version of FreeBSD that currently ships with its own Qt5-powered Lumina Desktop Environment while also having a server installer, etc. The folks working on TrueOS at iXsystems are now planning to take TrueOS into a new direction.

Ahead of its expected release by month's end, FreeBSD 11.2 is now in the release candidate phase of development.

For those of you with some extra time over this US holiday weekend due to Memorial Day, FreeBSD 11.2 Beta 3 is now available for testing.

While DragonFlyBSD 5.3/5.4 is exciting on the performance front for those making use of the stable DragonFly operating system releases, DragonFlyBSD 5.2.1 is available this week.

The second beta release of FreeBSD 11.2 is now available for weekend testing.

FreeBSD 11.2 has reached the beta milestone to succeed FreeBSD 11.1 from last year and ahead of FreeBSD 12.0 that is expected this November.

DragonFlyBSD lead developer Matthew Dillon has just pushed out DragonFly's Spectre mitigation code as well as fixing "CVE-2018-8897" which is what might be the recently rumored "Spectre-NG" vulnerabilities.

Following years of work in bringing the KDE Plasma 5 desktop to FreeBSD, it's getting into shape and the x11/kde5 package is now in the ports tree for easing the process of setting up the modern KDE desktop stack.

The Arcan Display Server that is the display stack built off (in part) a game engine and also developing the Durden desktop and most recently developing a "Safespaces" VR Linux desktop has also been working on porting the code from Linux to OpenBSD.

Last week I wrote about the NetBSD 8.0 RC1 images being available and the changes coming in this big update to this popular BSD platform. This morning that official NetBSD 8.0 RC1 announcement was issued.

DragonFlyBSD has implemented a portion of the Linux IRQ subsystem within its kernel.

While in recent months there have been some improvements to FreeBSD that have helped yield greater reliability in running AMD Ryzen processors on this BSD operating system, some users are still reporting hard to diagnose stability problems on FreeBSD.

It looks like the DragonFlyBSD 5.4 release will be delivering at least a few kernel-level performance improvements.

It's a busy month for the BSDs with DragonFlyBSD 5.2 having come along with OpenBSD 6.3 and right before that was TrueOS 18.03. Now there's finally the release candidate of the long-awaited NetBSD 8.0 update.

Besides the fresh BSD/Linux disk performance tests, some other tests I ran on various BSDs and Linux distributions this week was looking at the performance impact of Intel Meltdown CPU vulnerability mitigation on each of them, namely the performance impact of using kernel page-table isolation.

With the recent release of DragonFlyBSD 5.2 one of the prominent changes is HAMMER2 now being considered stable for most use-cases. I've been running some benchmarks of this file-system compared to alternatives on other operating systems and have some FreeBSD / Linux reference points to share.

Besides looking at the HAMMER2 performance in DragonFlyBSD 5.2, another prominent change with this new BSD operating system release is the Spectre and Meltdown mitigations being shipped. In this article are some tests looking at the performance cost of DragonFlyBSD 5.2 for mitigating the Meltdown Intel CPU vulnerability.

In addition to the overhauled/rewritten Windows support, the upcoming Phoronix Test Suite 8.0-Aremark is also featuring much better support for the BSDs. As part of that testing, here are some fresh benchmarks of FreeBSD and TrueOS.

DragonFlyBSD 5.2 is now available as the latest installment of this popular BSD operating system.

OpenBSD 6.3 hadn't been due until the middle of the month, but the official release of this popular BSD operating system is available today.

The crew working on the FreeBSD-derived TrueOS operating system formerly known as PC-BSD have put out a special release of their platform in order to ship the Spectre and Meltdown mitigations.

The first release candidate is now available of the upcoming DragonFlyBSD 5.2 operating system.

While FreeBSD has a Linux compatibility/emulation layer that allows it to run some Linux games, an independent community developer has been working on porting Epic Games' Unreal Engine 4 to FreeBSD.
