Five Years Of Linux Kernel Benchmarks: 2.6.12 Through 2.6.37

Filed under
Linux

While we have conducted studies related to the Linux kernel performance in the past such as benchmarking up to twelve kernel releases, going out the door this morning are the results from the largest-ever Linux kernel comparison conducted at Phoronix, and very likely the largest ever of its kind regardless of source. Every major Linux kernel release from Linux 2.6.12, which was released in mid-2005, up through the latest Linux 2.6.37 development code was tested. This represents the past five years of the Linux kernel and shows how the performance has evolved over the past 25 stable kernel releases and the most recent 2.6.37 development kernel.

Benchmarking 26 kernels was no easy feat with running nearly two dozen tests each time and each test being run multiple times (usually three to five times as a minimum). Fortunately, with the Phoronix Test Suite combined with an Intel Core i7 "Gulftown" made this process much faster, easier, and more reliable than what would otherwise have been possible.

In order to go back all the way to the Linux 2.6.12 kernel, which puts us to the era of Ubuntu 5.10, SuSE 9.3, Fedora Core 4, and Mandrake 2006 distributions, we decided to go with Fedora Core 4 as the base operating system. However, in order to run Fedora Core 4 on the Core i7 970 desktop system rather than 2005-era hardware where this benchmarking process would have easily taken weeks, we ran all tests from within a Fedora Core 4 virtual machine. The Core i7 970 host system was running Ubuntu 10.10 64-bit with the Linux 2.6.35 kernel on an ASRock X58 SuperComputer motherboard, 3GB of DDR3 system memory, a NVIDIA GeForce GTX 460, and a 64GB OCZ Vertex SSD.

Steam Controller Kernel Driver Is Landing In The Linux 4.18 Kernel

The Linux 4.18 kernel will feature the initial Steam Controller kernel driver that works without having to use the Steam client or using third-party user-space applications like the SC-Controller application. A few months back we reported on a kernel driver being worked on for the Steam Controller by an independent user/developer outside of the gates of Valve. In part through reverse-engineering, Rodrigo Rivas Costa has been working on this native Steam Controller Linux kernel driver that works for both USB cable and wireless modes of the Steam Controller and is a proper HID driver.

KDevelop 5.2.2 and 5.2.3 released

KDevelop 5.2.2 and 5.2.3 released We today provide a stabilization and bugfix release with version 5.2.2 and 5.2.3. 5.2.2 was tagged 6 weeks ago, but we never managed to release it because we did not have the patience to fix the Windows installers in time due to a broken CI. Windows installers are provided for 5.2.3 again. We'll only provide source tarballs for 5.2.2 and we encourage everyone to just skip this release and use 5.2.3 which contains a few more bug fixes. This is a bugfix-only release, which introduces no new features and as such is a safe and recommended update for everyone currently using KDevelop 5.2.1.
