A Look At The Relative Spectre/Meltdown Mitigation Costs On Windows vs. Linux

The latest in our Windows versus Linux benchmarking is looking at the relative performance impact on both Linux and Windows of their Spectre and Meltdown mitigation techniques. This round of tests were done on Windows 10 Pro, Ubuntu 18.04 LTS, and Clear Linux when having an up-to-date system on each OS where there is Spectre/Meltdown protection and then repeating the same benchmarks after reverting/disabling the security functionality.

Raspberry Pi 3 Model B+ WiFi Performance

Yesterday in our Raspberry Pi 3 Model B+ benchmarks we looked at the faster Cortex-A53 CPU cores of this new $35 USD ARM SBC as well as its much faster Ethernet and better thermal management over earlier Raspberry Pi boards. The other area improved with the Raspberry Pi 3 B+ is the WiFi/WLAN wireless networking, which is what we have benchmarks of today.

Wayland's Weston Getting New Touchscreen Calibrator

With Wayland appearing in more places from automobile in-vehicle infotainments to planes to smartphones, having a good touchscreen calibration system is certainly important. Collabora developers have been working on a new touchscreen calibrator and new protocol extension for Weston.

Fedora 28 Beta Has Been Delayed

It's time for the Fedora 28 release dance and to place your bets if F28 will be released on time or is another Fedora release challenged by release delays.

Raspberry Pi 3 Model B+ Benchmarks

Last week on Pi Day marked the release of the Raspberry Pi 3 Model B+ with a slightly higher clocked Cortex-A53 processors, dual-band 802.11ac WiFi, faster Ethernet, and other minor enhancements over its predecessor. I've been spending the past few days putting the Raspberry Pi 3 Model B+ through its paces the past few days with an array of benchmarks while comparing the performance to other ARM SBCs as well as a few lower-end Intel x86 systems too. Here is all you need to know about the Raspberry Pi 3 B+ performance.

Windows 10 vs. Ubuntu Linux With Radeon / GeForce GPUs On The Latest 2018 Drivers

Given how fiercely the latest open-source AMD Linux driver code is running now up against NVIDIA's long-standing flagship Linux GPU driver, you might be curious how well that driver stacks up against the Radeon Software driver on Windows? Well, you are in luck as here are some fresh benchmarks of the Radeon RX 580 and RX Vega 64 as well as the GeForce GTX 1060 and GTX 1080 Ti while being tested both under Microsoft Windows 10 Pro x64 and Ubuntu 16.04 LTS while using the latest AMD/NVIDIA drivers on each platform.

Mesa 17.3.7 Released With A Bunch Of Fixes

While Mesa 18.0 should finally be out on Friday as the major quarterly update to the Mesa 3D drivers, Mesa 17.3.7 is out today and it's a rather big update for being just another point release to last month's 17.3 series.

Fresh Benchmarks Of CentOS 7 On Xeon & EPYC With/Without KPTI/Retpolines

While every few weeks or so we have ended up running benchmarks of the latest Linux Git kernel to see the evolving performance impact of KPTI (Kernel Page Table Isolation) and Retpolines for Meltdown and Spectre V2 mitigation, respectively, a request came in last week from a premium supporter to see some new comparison test runs on CentOS 7 with its older 3.10-evolved kernel.

xf86-input-libinput 0.27.0 Released

Aside from a few touchpad issues and other minor random issues with select hardware, libinput these days is mostly in great shape for being a generic input handling library that is working out well for both X.Org and Wayland users.

Radeon GPUs Are Increasingly Competing With NVIDIA GPUs On Latest RadeonSI/RADV Drivers

As it's been a few weeks since last delivering a modest Linux GPU comparison and given the continuously evolving state of the Linux kernel Git tree as well as the Mesa project that houses the RadeonSI OpenGL and RADV Vulkan drivers, here are our latest benchmarks showing the current state of the AMD Radeon open-source Linux graphics driver performance relative to NVIDIA's long-standing and high-performance but proprietary driver using several different graphics cards.

Ubuntu 18.10 Looking At LZ4-Compressed Initramfs Image By Default

With Ubuntu 18.10 being the release after an LTS cycle, it's shaping up to be another big feature period. They have already been discussing Zstd-compressed Debian packages for Ubuntu 18.10 while the latest proposal for this next cycle is on switching from Gzip to LZ4 for the default kernel initramfs image.
