Besides disabling CPU security mitigations (not recommended if security is of importance), for those wanting to squeeze extra performance out of Intel CPUs like Comet Lake with the Core i9 10900K, loading Intel's performance-optimized Clear Linux is one such way. Here is a look at the current performance that can be gained out of using the latest rolling-release Clear Linux on the i9-10900K in comparison to Ubuntu 20.04 LTS.

While most of you are well aware how Linux often slaughters Microsoft Windows performance on high-end desktop and platform servers with large core counts, on smaller systems it can be a different story and often comes down to the particular workloads and any peculiarities of the hardware under test. With recently buying the Lenovo IdeaPad 5 (14) for our AMD Ryzen 7 4700U Linux benchmarking, here are some benchmarks for how that Zen 2 laptop is comparing with different workloads between Windows 10 and Ubuntu 20.04 LTS.

A Phoronix Premium reader recently asked about whether Pop!_OS 20.04 performance differs from Ubuntu 20.04 given some underlying changes made by System76 to their distribution, besides the plethora of higher-level desktop improvements. Well, here are some benchmarks.

Given the recent releases of Fedora 32, Ubuntu 20.04 LTS, Manjaro 20.0, and others, here is a fresh eight-way Linux distribution benchmark comparison.

After showing yesterday how the performance has changed from Fedora 31 to Fedora 32, you may be wondering about how Fedora 32 -- which is due to be released next week -- stacks up against the brand new Ubuntu 20.04 LTS release. Here are the results from dozens of benchmarks and with some areas seeing some clear performance differences.

System76 has released the 20.04 beta of their Ubuntu-based Pop!_OS Linux distribution. This release comes with various improvements and in this article are some initial benchmarks of Pop!_OS 20.04 beta compared to their prior 19.10 release when testing on the System76 Thelio Major with AMD Ryzen Threadripper 3990X.

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 Ubuntu 20.04 due for release next week, here is a look at how the various CPU vulnerability mitigations compare on that latest Linux software stack when comparing the out-of-the-box mitigations for Spectre, Meltdown, and friends, compared to booting with "mitigations=off" for disabling those mitigations. The desktop tests were done with Intel and AMD processors for reference.

There is less than one month to go until the official release of Ubuntu 20.04 LTS "Focal Fossa" but we've already begun experimenting with it for weeks across a variety of platforms. For the most part we have found Ubuntu 20.04 slated to offer some nice performance improvements, especially if upgrading from the existing LTS series, Ubuntu 18.04. In this article are our initial benchmarks looking at the Intel Xeon Scalable from Ubuntu 18.04 LTS to the current 20.04 near-final state.

Given the release earlier this month of DragonFlyBSD 5.8 along with the recent debut of the FreeBSD-based desktop-focused GhostBSD 20.02, here are benchmarks looking at their performance up against FreeBSD 12.1-RELEASE as well as the current state of Ubuntu 20.04. Tests were done both with the LLVM Clang and GCC compilers.

We are used to seeing tier-one Linux distributions outperforming Microsoft Windows on hardware ranging from $199 laptops to HEDT and server processors and everything in between. Thus it came as a large surprise to us when finding Windows 10 outperforming multiple Linux distributions on a new Intel laptop. Not only was Windows 10 leading, but the performance paradigm shifted that Ubuntu was even outperforming Clear Linux, which normally is the fastest of Linux distributions out-of-the-box.

While we have been seeing Ubuntu 20.04 LTS offer better performance with newer hardware platforms, how does the performance compare to Intel's performance-optimized Clear Linux? Here are some benchmarks on both AMD Ryzen 9 3900X and Intel Core i9 9900KS systems.

While Ubuntu is based on Debian, for those wondering how the performance of Ubuntu 20.04 LTS is looking not only compared to the previous 19.10 and 18.04.4 LTS releases but also Debian 10.3 stable and Debian Testing, here are some benchmark results on an AMD Ryzen 9 3900X system.

Particularly for those on Ubuntu 18.04 LTS or derivative distributions based on the current long-term support base, moving to Ubuntu 20.04 LTS due out next month will yield some nice improvements particularly for those on newer platforms like the AMD Ryzen 3000 series. Here are some benchmarks at how the Ryzen 9 3900X performance is looking between Ubuntu 18.04.4 LTS, Ubuntu 19.10, and the current Ubuntu 20.04 LTS development snapshot.

Intel's performance-oriented Clear Linux distribution recently added support for using F2FS as the root file-system so we were curious to run some benchmarks on it for how it stacks up against EXT4.

While Clear Linux is well known as being the performance-optimized Linux distribution out of Intel and catered towards performing the best on their hardware (though as we continue to show, Clear Linux does also perform incredibly well on AMD hardware too and generally faster than other distributions), when it comes to AMD-optimized distributions the primary example remains OpenMandriva. Since 2018 OpenMandriva has been providing an AMD Zen optimized build where their operating system and entire package archive is built with the "znver1" compiler optimizations. As it's been almost a year since last looking at OpenMandriva's Zen optimized build, here are some fresh benchmarks using the newly-released OpenMandriva 4.1.

Last week I looked at the Windows vs. Linux scaling performance on the Threadripper 3990X at varying core/thread counts followed by looking at the Windows 10 performance against eight Linux distributions for this $3990 USD processor running within the System76 Thelio Major workstation. Now the tables have turned for our first look at this 64-core / 128-thread processor running on the BSDs, FreeBSD 12.1 in particular. With this article is looking at the FreeBSD 12.1 performance and seeing how the performance scales compared to Ubuntu 20.04 Linux and the Red Hat Enterprise Linux 8 based CentOS Stream.

Motivated by last week's Windows vs. Linux benchmarks with the 128-thread AMD Ryzen Threadripper 3990X here are Windows 10 Pro and Enterprise benchmarks on the 32-core / 64-thread AMD Ryzen Threadripper 3970X up against eight Linux distributions.

One of the interesting takeaways from my pre-launch briefing with AMD on the Ryzen Threadripper 3990X was AMD representatives actually recommending Clear Linux for use on this 64-core / 128-thread HEDT processor and the platform to which they've found the best performance. Yet, Clear Linux is an Intel open-source project. In any case, here are benchmarks of how Clear Linux performs against other Linux distributions on the Ryzen Threadripper 3990X within the System76 Thelio Major. And, holy crap, with the Threadripper 3990X on Clear Linux I managed to build the x86_64 default Linux kernel in under 20 seconds!

The Linux 5.6 merge window is anticipated to be ending today followed by the Linux 5.6-rc1 test release. This kernel is simply huge: there is so many new and improved features with this particular release that it's mind-boggling. I'm having difficulty remembering such a time a kernel release was so large.

The latest in our benchmarking fun with the $199+ Motile M141 laptop is seeing how well Intel's Clear Linux performs on it in relation to Ubuntu and Fedora.

As part of our many Linux benchmarks in ending out the 2010s we ran tests looking at CentOS 6 through CentOS 8, seven years of Ubuntu Linux performance, and various other Linux distribution benchmarks and testing other important pieces of open-source software over time. One of the additional comparisons now wrapped up is looking at the performance of Debian GNU/Linux going back from the old 7 series through the current 10 stable series and also Debian Testing. Tests where relevant were done out-of-the-box with the default security mitigations and again with mitigations disabled.

Earlier this month many Phoronix readers were interested in our fresh tests of the XanMod-patched Linux kernel for boosting the desktop and workstation performance compared to Ubuntu's default Linux kernel. Among many patches, XanMod does pull in some kernel patches from Intel's performance-optimized Clear Linux, so we figured it would be interesting to see how the XanMod'ed Ubuntu compares to Clear Linux performance.

It's been four years since last testing out the XanMod kernel as a spin of the Linux kernel with various patches and extra tuning designed to offer better desktop/workstation performance, similar to the Liquorix kernel. But given the recent Liquorix kernel testing and discussions over kernel schedulers and more, here are some fresh benchmarks of the latest XanMod kernel. Long story short, I am quite impressed by these latest XanMod results.

Your choice of Linux distribution on a budget PC can mean the difference of ~14% performance overall. Here are benchmarks of Ubuntu, CentOS, Debian, EndeavourOS, Manjaro Linux, openSUSE Tumbleweed, Fedora Workstation, and Clear Linux on a $50 processor as we roll into 2020 with the newest Linux distribution releases.

Last week I posted benchmarks looking at the performance of Intel's Clear Linux over the course of 2019 with roughly 7% better performance across dozens of benchmarks on the same system. But how does that compare to other Linux distributions with the same hardware? Here is a look in showing the performance for both Fedora and Ubuntu at the end of 2018 to the end of 2019.

The latest in our series of interesting year-end benchmarks -- made more interesting by also looking at the Linux performance over the 2010s -- is looking at the performance of Ubuntu Linux over the past roughly seven years by re-testing all the releases. Ubuntu 19.10 stable and Ubuntu 20.04 LTS development builds were tested along with the Ubuntu releases going back to Ubuntu 13.04, the initial release where the Intel Sandy Bridge support was in good shape for the Core i7 2700K platform being used for this round of benchmarking. It's quite a wild ride looking at the Ubuntu performance over this long span with dozens of different workloads.

While the AMD Ryzen Threadripper 3970X is delivering better raw Linux performance in a far majority of workloads compared to the Intel Core i9 10980XE, one of the areas where the Cascadelake-X platform and Intel CPUs still have an advantage is when it comes to the BSD support. Intel actively supports the BSDs more than AMD and in turn leads to the latest hardware generally working out fine on the latest BSDs. Here are some DragonFlyBSD and FreeBSD tests against Linux with the i9-10980XE.

While Alpine Linux has traditionally been a lightweight Linux distribution focused on use within containerized environments, with yesterday's release of Alpine Linux 3.11 brought GNOME and KDE support for those wanting to use this distribution as a desktop/workstation OS. Curious, I had to give it a try and of course run some general Alpine Linux 3.11 benchmarks up against Clear Linux and Ubuntu 19.10 for seeing how its performance is on bare-metal hardware.

A few weeks back having done Threadripper 3970X Windows vs. Linux benchmarks for seeing how the competing operating systems are performing, following the recent i9-10980XE 11-way Linux distributions tests I loaded up Microsoft Windows 10 Pro November 2019 Update... Here are those benchmarks for those wondering how the Cascadelake-X platform is running in Windows vs. Linux performance.
