If all goes according to plan, the Linux 4.2 kernel merge window will close this afternoon followed by the immediate release of the Linux 4.2-rc1 test version. With all major pull requests having already been submitted for Linux 4.2, here's an overview of the exciting new features and changed functionality to look forward to with this kernel version to officially debut later this summer!
With the Linux 4.1 kernel having recently been released, I decided to conduct a fresh round of file-system comparisons on this new kernel using a solid-state drive. The file-systems tested in this article were the in-tree EXT4, Btrfs, XFS, F2FS, ReiserFS, and NILFS2 file-systems while a follow-up article will take a look at the out-of-tree contenders like Reiser4 and ZFS atop Linux 4.1.
One of the most often voiced complaints about Open Source Software is that it tends to be "ugly" or otherwise aesthetically uninspired. A few years ago a few people in the KDE camp came together and created, what they hoped, would be a solution to that problem: The KDE Visual Design Group.
Besides presenting a lot of new kernel features and functionality, the upcoming Linux 4.1 kernel release is potentially very exciting if you're an owner of certain classes of Intel hardware that offer better performance under this new kernel -- and in some cases, better battery life. Here's some tests from yet another system I found exhibiting some promising results from this new 2015 summer kernel version.
Phoronix Test Suite 5.8 was released today as the latest quarterly update to Phoronix Media's open-source, cross-platform benchmarking and automated testing software. Beyond offering a significant number of new features, the Phoronix Test Suite 5.8 release commemorates seven years since the release of Phoronix Test Suite 1.0 and eleven years since the start of Phoronix.com in what's evolved to become the largest Linux hardware destination on the Internet.
For a few months now I've been talking about the LinuxBenchmarking.com initiative to provide daily benchmark results of the latest development Git/SVN code for various open-source projects in a fully-automated manner... Among the projects being tracked have been the Linux kernel, GCC, LLVM Clang, etc. There's dozens of systems at Phoronix Media in "the basement server room" doing nothing but running these upstream benchmarks day in and day out. The data flow is now open at LinuxBenchmarking.com.
There's numerous recent features to talk about this weekend for those interested in tracking Linux system performance, monitoring upstream projects for performance regressions, and carrying out other similar work using open-source software on Linux / BSD / OS X / Solaris.
Today's post by the new Phoronix intern is looking at the state of various new (and experimental) features within Mozilla's Firefox web-browser. Covered in this article is the Electrolysis e10s multi-process model, Encrypted Media Extensions, Media Source Extensions, Skia, off-main thread compositing, and sandboxing.
A few days ago I ran some fresh hard drive file-system benchmarks on Linux 4.0 and today those results are being complemented by the solid-state drive results. Tested on the SSD were the popular EXT4, Btrfs, XFS, and F2FS file-systems.
It's been a while since last running any Linux file-system tests on a hard drive considering all of the test systems around here are using solid-state storage and only a few systems commissioned in the Linux benchmarking test farm are using hard drives, but with Linux 4.0 around the corner, here's a six-way file-system comparison on Linux 4.0 with a HDD using EXT4, Btrfs, XFS, and even NTFS, NILFS2, and ReiserFS.
Phoronix Test Suite 5.6 was released today as the quarterly update to Phoronix Media's open-source, cross-platform benchmarking and automated testing software.
For those that may soon be upgrading to the recently released Linux 3.19 kernel, here's some file-system tests comparing EXT4, Btrfs, XFS, and F2FS on a solid-state drive compared to Linux 3.18.
My latest Intel Broadwell Linux benchmarks are looking at the performance of the in-development GCC 5 compared to GCC 4.9, the current stable release shipped by many Linux distributions throughout 2014.
Another day, another round of Intel Broadwell Linux benchmarks. Being looked at this morning are some GCC vs. Clang compiler benchmarks for this latest Intel microarchitecture succeeding Haswell.
The release of LLVM 3.6 is expected next month as a significant step forward to this innovative compiler infrastructure. For those curious how its performance is shaping up, I've carried out some fresh LLVM Clang 3.5 vs. LLVM Clang 3.6-rc1 benchmarks this weekend.
Phoronix Test Suite 5.4-Lipki is released to end out another year of improving open-source and Linux benchmarking. Phoronix Test Suite 5.4 features the next-generation, open-source Phoromatic server and client software.
With the Linux 3.18 development settling down, here's our usual benchmarks of the new kernel when comparing the file-system performance against the previous stable version (Linux 3.17) for EXT4, F2FS, XFS, and Btrfs.
In celebration of Ubuntu 14.10's Utopic Unicorn release today, here's some fresh benchmarks of one of the most requested topics: 2D/3D benchmarks of different desktop environments. In this article is a look at six of the popular desktop offerings found in Ubuntu 14.10.
With this week's Fedora 21 Alpha release delivering the very latest open-source Linux graphics driver code, the newest Wayland code, and the updated GNOME 3.14 desktop with its day-to-day support for Wayland, I've been busy benchmarking.
With the Linux 3.17 kernel due out soon, here's our routine file-system benchmarks we do each kernel cycle to see how the popular Linux file-systems have evolved between kernel releases.
Continuing in our recent CPUFreq vs. P-State scaling driver benchmarks, here's some tests from the eight-core Core i7 5960X Haswell-E system as we test the two CPU frequency scaling drivers and their different governors.
With X.Org Server 1.16 having landed in Ubuntu 14.10, it's time for some benchmarks comparing the 1.15 and 1.16 releases on Ubuntu while using the GLAMOR 2D acceleration library.
Sunday benchmarks this week on Phoronix are comparing nine popular, mainline file-systems present within the Linux 3.17 kernel. All the usual contenders are present and the benchmarks happened with a solid-state disk.
In adding some extra tests besides what was shared in our large Linux review of the new AMD FX CPUs from earlier in the week, that included a fairly big comparison of Intel and AMD CPUs, here's some more Linux test results for just the FX-8370E, FX-8370, and FX-9590 processors.
In anticipation of the LLVM 3.5 release that brings a number of new compiler features -- including possible performance improvements from our benchmarking done earlier today -- here's some benchmarks comparing LLVM Clang 3.5 RC3 to a recent SVN snapshot of the GCC 5.0 compiler that's presently under development.
If all goes well, LLVM 3.5 will be released today. While we have already delivered some LLVM/Clang benchmarks of the 3.5 SVN code, over the days ahead we will be delivering more benchmarks of the updated compiler stack -- including looking at its performance against the in-development GCC 5.0. For getting this latest series of compiler benchmarking at Phoronix started, here's some fresh numbers of LLVM Clang 3.4 compared to a recent release candidate of LLVM Clang 3.5.
As I wrote about yesterday, there appears to be a new Linux kernel power regression that's yet to be solved by the latest Linux 3.17 code. The issue was originally tracked down to being a regression introduced during the Linux 3.15 stable cycle that disabled frame-buffer compression support by default for the Intel DRM graphics driver, but the impact it's had on the system power draw is much greater than what was anticipated by the Intel developers. A separate Intel employee is also reporting increased power draw, so I decided to run some tests on a few local systems to see what I'm encountering in the power consumption primarily between Linux 3.15 and 3.16.
In past months on Phoronix we have done many CPUfreq tests to see the impact of the different scaling governors and with Intel hardware how the CPUfreq driver compares to Intel P-State in terms of performance and power consumption. As we haven't done such ACPI CPUfreq tests on the AMD side in a long time, here's some benchmarks using a Kaveri APU and selecting the different scaling governors during performance benchmarking.
For those wondering about the modern performance cost of using KVM on Ubuntu Linux for virtualizing a guest OS, here are some simple benchmarks comparing Ubuntu 14.10 in its current development stage with the Linux 3.16 versus running the same software stack while virtualized with KVM and using virt-manager.
After a last minute delay earlier this month, Keith Packard of Intel's Open-Source Technology Center has officially announced the X.Org Server 1.16 release. XWayland and other changes make xorg-server 1.16 a super exciting release!
