Fresh Docker Linux Benchmarks For Summer 2018

Following the recent rounds of Linux distribution benchmarking with Windows Server vs. FreeBSD vs. Linux, Windows vs. Linux laptop benchmarks, and other recent comparisons, one of the latest requests was a fresh look at the performance of different Linux distributions deployed within Docker containers.

A 3.3x Performance Improvement For FLAC Audio Encoding On POWER 64-bit

In last month's round of IBM POWER9 benchmarking on the Talos II systems compared to various Intel/AMD x86_64 CPUs, one of the areas where POWER was struggling especially was with multimedia encoding performance. Fortunately, since those POWER9 Phoronix benchmarks this year, various developers have been working on optimizations.

2018 Brings A New Linux X.Org Display Driver Update For The ATI RAGE 128

Last month I wrote about a new attempt at improving the ATI RAGE 128 X.Org driver... Yes, for the for the Rage graphics cards from the late 90's in the days of AGP and PCI where core/memory clock speeds were commonly in the double digits... If you are a hobbyist fond of these vintage graphics cards and are still running with these OpenGL 1.1~1.2 capable GPUs, there is a new X.Org driver update.

A Fresh Look At The PGO Performance With GCC 8

It's been a while since we last ran some GCC PGO benchmarks, the Profile Guided Optimizations or feedback-directed optimization technique that makes use of profiling data at run-time to improve performance of re-compiled binaries. Here are some fresh benchmarks of GCC PGO impact on a Xeon Scalable server while using the newly-released GCC 8.2 release candidate.

Freedreno Gallium3D Now Exposes Adreno A5xx Performance Counters

It's been a while since last having any news to report on Freedrenon, the open-source, community-driven Gallium3D driver for providing accelerated 3D support for Qualcomm Adreno graphics hardware. But ahead of the upcoming Mesa 18.2 feature freeze, Freedreno founder Rob Clark has been landing a number of improvements.

Ubuntu 18.04.1 LTS Introducing Revised Server Installer, Adds Missing Features

With the April release of Ubuntu 18.04 LTS on the server front was a brand new, in-house developed server installer created by Canonical to differentiate it from Debian's long-used text installer for the Ubuntu Server images. While it offered a fresh look and some new features, it shipped without many features common to Linux server installers. Fortunately, that is changing with the upcoming Ubuntu Server 18.04.1 release.

Linux To Better Protect Entropy Sent In From User-Space

Fedora has begun utilizing a user-space jitter entropy daemon for feeding entropy to the kernel at boot time in case not enough is available for the kernel's random needs. But with that approach not being from a true hardware random number generator, a patch worked out by veteran Linux kernel developer Ted Ts'o will mix in RdRand entropy.

System76 Moves Ahead With Preparing To Manufacture Their Own Desktop Linux PCs

Back in April 2017 was the announcement that System76 would begin designing and manufacturing their own systems beginning with desktops and to be followed at a later date by their own laptops, rather than relying upon whitebox designs that they currently retail with their Ubuntu/Pop!_OS-loaded PCs. The Colorado-based company is inching closer to fully realizing their goal.

IT87 Linux Driver For Supporting Many Motherboard Sensors Is Facing Death

While Linux hardware support for desktop PCs has advanced a great deal over the years, one area that continues to struggle is support for fan/thermal/power sensors on many of today's motherboards. This area has struggled with not enough public documentation / data-sheets from ASIC vendors as well as not enough upstream Linux kernel developers being interested in the hwmon subsystem. The IT87 Linux driver for many common Super I/O chips found on countless motherboards is unfortunately facing a downfall.

Dell XPS 13: Windows 10 vs. Linux Distribution Benchmarks

Recently I have published benchmarks looking at Windows Server and FreeBSD against eight Linux distributions as well as a 9-way Linux desktop OS benchmark comparison while the latest in this string of fresh Linux distribution benchmarks is looking at the Linux laptop performance impact, if any, between these operating systems. Up for this benchmarking dance was Microsoft Windows 10, Windows 10 when running Ubuntu 18.04 via WSL, Ubuntu 18.04 itself, Fedora Workstation 28, openSUSE Tumbleweed, and Clear Linux.

Lubuntu Needs Help Testing For 32-bit x86 Support To Continue

While Ubuntu and most of its derivatives have stopped producing 32-bit x86 images with the number of devices out there dwindling that can't run x86_64, Lubuntu is among the few still offering i686 images to help those who may be running on outdated hardware but still interested in running the latest Linux software.
