Red Hat Enterprise Linux 8.0 Benchmarks On AMD EPYC - Big Speed-Ups Over RHEL7

Since the release of Red Hat Enterprise Linux 8.0 at the start of May we've been running various benchmarks of this latest enterprise Linux platform. Our tests to date have been with Intel Xeon hardware where it's been performing well and a nice speed-up over RHEL 7 with modern Xeon Scalable CPUs. Similarly, AMD EPYC is also much faster with RHEL 8.0 thanks to the much newer Linux kernel, compiler, and other software updates.

Red Hat Enterprise Linux 8.0 Benchmarks Against RHEL 7.6, Ubuntu 18.04.2 LTS, Clear Linux

Continuing on from the initial Red Hat Enterprise Linux 8.0 benchmarks last week, now having had more time with this fresh enterprise Linux distribution, here are additional benchmarks on two Intel Xeon servers when benchmarking RHEL 8.0, RHEL 7.6, Ubuntu 18.04.2 LTS, and Clear Linux. RHEL 8.0 is certainly delivering much better out-of-the-box performance than its aging predecessor but how can it compete with Ubuntu LTS and Clear Linux?

Fedora 30 Performance Is Moving In The Right Direction But A Lot Of Untapped Potential

Yesterday we began with our preliminary performance benchmarks of Fedora 30. From those results Intel Core i9 and AMD Threadripper systems and what we're seeing on other systems in the labs, Fedora 30 indeed is coming out generally slightly faster than Fedora 29 when looking at the performance overall. In some cases the performance is much better thanks to GCC 9 and other upgrades, but overall it's a small, modest performance improvement. While that's better than seeing Fedora 30 running slower than its predecessor, there still is more potential to squeeze out of the system.

Ubuntu 19.04 Is Offering Some Performance Improvements Over Ubuntu 18.10, Comparison To Clear Linux

With the Ubuntu 19.04 "Disco Dingo" release less than one month away, we are getting ready for rolling out more tests of this next six-month installment to Ubuntu Linux. For those curious about the direction of Ubuntu 19.04's performance, here are some very preliminary data points using the latest daily state of Ubuntu 19.04 right ahead of the beta period. Tests were done on a high-end Intel Core i9 9900K desktop as well as a Dell XPS Developer Edition notebook when comparing Ubuntu 19.04 to Ubuntu 18.10 and also tossing in Clear Linux as a performance reference point.

Spectre/Meltdown Performance Impact Across Eight Linux Distributions

While nearly all Linux distributions have been mitigated against the Spectre and Meltdown CPU vulnerabilities for over one year, the performance ahead associated with these speculative execution vulnerabilities can vary. This is especially more so with the enterprise Linux distributions that are generally shipping on older kernel branches prior to where the initial kernel support was mainlined. With recent kernel releases we've also seen varying optimizations and other changes around the Spectre/Meltdown/L1TF mitigations. So for those wondering about the varying impact, here are some side-by-side benchmarks.

Using Clear Linux As A Desktop Linux Distribution - It Works Well But With Some "Papercuts"

While I am a big fan of Intel's Clear Linux distribution for its raw performance on x86_64 hardware that for most workloads goes unsurpassed by any other Linux platform out-of-the-box, there has been a lot of Phoronix readers wondering how well it could function as a standard desktop Linux distribution. With upgrading my main production system earlier this month, I decided to try out Clear Linux and now with 200+ hours into using it as the OS on my main production system, I figured it'd be good to share my initial thoughts.

Ubuntu vs. Debian vs. openSUSE On The POWER9 Raptor Talos II

While we frequently compare the performance of many x86_64 Linux distributions, we haven't done one under IBM POWER9 since getting our hands on the Raptor Computing Systems' Talos II back in November. It's been very interesting to benchmark this libre hardware that's high performance with having 44 cores / 176 threads at 3.80GHz. But how much more performance can be tapped by using other Linux distributions? Here's a look with some of the current POWER9 Linux distribution options.

FreeBSD 12.0 vs. DragonFlyBSD 5.4 vs. TrueOS 18.12 vs. Linux On A Tyan EPYC Server

Last month when running FreeBSD 12.0 benchmarks on a 2P EPYC server I wasn't able to run any side-by-side benchmarks with the new DragonFlyBSD 5.4 as this BSD was crashing during the boot process on that board. But fortunately on another AMD EPYC server available, the EPYC 1P TYAN Transport SX TN70A-B8026, DragonFlyBSD 5.4.1 runs fine. So for this first round of BSD benchmarking in 2019 are tests of FreeBSD 11.2, FreeBSD 12.0, DragonFlyBSD 5.4.1, the new TrueOS 18.12, and a few Linux distributions (CentOS 7, Ubuntu 18.04.1 LTS, and Clear Linux) on this EPYC 7601 server in a variety of workloads.

Five-Way Linux OS Comparison On Amazon's ARM Graviton CPU

Last month Amazon rolled out their "Graviton" ARM processors in the Elastic Compute Cloud. Those first-generation Graviton ARMv8 processors are based on the ARM Cortex-A72 cores and designed to offer better pricing than traditional x86_64 EC2 instances. However, our initial testing of the Amazon Graviton EC2 "A1" instances didn't reveal significant performance-per-dollar benefits for these new instances. In this second round of Graviton CPU benchmarking we are seeing what is the fastest of five of the leading ARM Linux distributions.
