Last week I posted some initial tests and benchmarks of DragonFlyBSD/FreeBSD on the AMD Threadripper 2990WX. While that went well and the BSDs scale with this 32-core / 64-thread processor better than Windows, lead DragonFly developer Matthew Dillon had picked up a 2990WX system and has been tuning the kernel ever since. Here are some benchmarks looking at some of his recent optimizations...

Raptor Computer Systems began their open-source hardware expedition with the POWER8-based Talos Secure Workstation that was quite expensive but last year launched the Talos II platform with IBM POWER9 processors and earlier this year launched the Raptor Talos II Lite systems at a cheaper price-point but still quite a significant investment compared to x86_64 AMD/Intel products. They've been pushing ahead on making their platform more viable for Linux users as well as more affordable and it looks like they will soon be launching a new product...

One of the most frequent test requests recently has been to look at the overall performance cost of Meltdown/Spectre mitigations on the latest Linux kernel and now with L1TF/Foreshadow work tossed into the mix. With the Linux 4.19 kernel that just kicked off development this month has been continued churn in the Spectre/Meltdown space, just not for x86_64 but also for POWER/s390/ARM where applicable. For getting an overall look at the performance impact of these mitigation techniques I tested three Intel Xeon systems and two AMD EPYC systems as well as a virtual machine on each side for seeing how the default Linux 4.19 kernel performance -- with relevant mitigations applied -- to that of an unmitigated kernel.

Announced last October was a 24-core ARM developer box being worked on by Linaro/96Boards, Socionext, and Gigabyte. The specifications are appealing with twenty-four ARM 64-bit cores with the SoC on a micro-ATX sized motherboard, support for a PCI Express graphics slot, and onboard Gigabit Ethernet. Here are our first benchmarks of this Socionext 96Boards Developerbox.

Word this week of the NVIDIA Jetson Xavier Development Kit being up for pre-order reminded me of some benchmarks I had been meaning to do of seeing how the NVIDIA Jetson TX2 developer kit's performance has evolved since its launch a year and a half ago. There's actually a quite measurable improvement in performance with the latest software/drivers compared to it was at launch.

For those looking at affordable metal server racks / open rack cabinets, I continue to be quite impressed by the StarTech.com four-post server racks. Recently I commissioned two more of their 12U racks in order to accommodate the latest Threadripper 2 systems in our Linux benchmarking farm...

You should likely be familiar with WebAssembly as the binary format for executing code within web pages that can be nearly as fast as running native machine code -- and certainly much faster than JavaScript. A new research project has been exploring running WebAssembly in the CPU's Ring 0 -- yes, the highest privileged state of the processor -- in the name of better performance...

Last week NVIDIA released the 396.54 driver that has a significant performance fix for OpenGL/Vulkan Linux performance due to a resource leak regression introduced at the start of the 390 driver series. With that updated driver (also as of yesterday back-ported to 390.87 too), there is a measurable boost in performance after running a few games on NVIDIA Linux systems. But at the same time, the Mesa 18.3-dev open-source graphics driver stack with RadeonSI/RADV continues improving on the open-source AMD front. Here is a fresh look at how the latest AMD Radeon and NVIDIA GeForce graphics cards compare using these latest drivers.

Given Valve's now public Steam Play for Linux using the Wine-derived Proton and their ongoing relationship with Code Weavers to improve the experience for Windows games on Linux, it perhaps adds better context why this summer for GSoC there was the automated Direct3D game benchmarking work with mentorship by a CodeWeavers developer...

In addition to the VKMS driver for virtual kernel mode-setting, the other successful Google Summer of Code (GSoC) project this summer under the X.Org umbrella was improving the DRM GPU scheduler...

While the Linux 4.19 kernel merge window just ended this past weekend and the development cycle for Linux 4.20 (or most likely to be called Linux 5.0) won't kick off until around the middle of October, AMD has already begun staging a ton of changes for this next kernel version. In particular, it looks like with this next kernel release their Vega 20 enablement will be in order...
