FreeBSD developers have been working on transitioning to using OpenZFS as their ZFS file-system upstream code rather than the dormant Illumos base. That initial FreeBSD support has been mainlined this week into the OpenZFS repository, now providing a common code-base between for the open-source ZFS file-system code between Illumos, FreeBSD, Linux, and work-in-progress macOS...

AMD has finally released their first "Radeon Software for Linux" packaged driver release to succeed their Radeon Software for Linux 19.50 driver series that saw its last update in December.

With Linux 5.7 the kernel is preparing to use the Schedutil governor more often on Intel systems. That change affects the CPUfreq default as well as the Intel P-State driver when in passive mode. While Schedutil holds a lot of hope, at least on Linux 5.7 with the testing I've done thus far the results show the raw performance slipping while testing on more platforms is forthcoming.

It turns out our recent OpenJDK 8 through OpenJDK 14 benchmarks caught some on Oracle's Java team by surprise. But they were able to replicate the outcome and as a result OpenJDK 15 will be seeing better out-of-the-box performance...

Earlier this week I published new benchmarks looking at the desktop CPU security mitigation impact with Ubuntu 20.04. Here are similar tests done in looking at the server mitigation impact with the near-final Ubuntu 20.04 LTS while testing server workloads on Intel Xeon and AMD EPYC server platforms. Like the desktop tests, the mitigation impact with the out-of-the-box protections against Spectre, Meltdown, and friends is being compared to booting the same Ubuntu 20.04 release with "mitigations=off" for run-time disabling of the relevant mitigations on each platform.

With Linux 5.6 the flash-focused F2FS file-system added LZO and LZ4 compression support for enhancing performance and ideally extending flash storage life by reducing the amount of writes. Added meanwhile for the current Linux 5.7 cycle was F2FS Zstd compression support. Now looking ahead to Linux 5.8, it looks like LZO-RLE support is being baked...

Released this month was the X-Plane 11.50 beta flight simulator that introduced a Vulkan renderer for this cross-platform, realistic flight simulator that long relied upon an OpenGL pipeline. Last week we published OpenGL vs. Vulkan X-Plane 11 benchmarks for both NVIDIA GeForce and AMD Radeon graphics. In this article is a look at the X-Plane 11.50 beta Vulkan performance across the different Radeon Vulkan driver options.

The AMD 7F52 processors we have been recently testing and offers some impressive performance potential as while it's a 16-core / 32-thread part it offers an impressive 256MB L3 cache (16MB per core). Here are our initial Linux benchmarks of the AMD EPYC 7F52 in 1P and 2P configurations up against various AMD EPYC and Intel Xeon processors.

One of the areas of Intel's Linux support that has been less than ideal is their handling of the Dynamic Platform and Thermal Framework (DPTF) for today's ultrabook. Intel has provided some support with a focus on Google's Chromium OS but it's less than complete and notably missing is support for the more advanced "adaptive policy", but that soon could change...
