Early Ubuntu 14.04 vs. Ubuntu 16.04 Intel Xeon E5 Benchmarks

Ubuntu

This morning I posted some Ubuntu 14.04 vs. 16.04 LTS Radeon graphics benchmarks while if open-source AMD graphics driver evolution doesn't get you excited, in this article are results from other non-graphics benchmarks in comparing the Ubuntu 14.04 vs. 16.04 performance for these long-term support releases in their current form.

For getting an idea how the overall Ubuntu Linux performance has evolved over the past two years for those solely riding Long-Term Support releases, I compared the performance of Ubuntu 14.04.0 to Ubuntu 16.04 LTS in its current daily ISO form. The tests were done on the same Intel Xeon E5-2687W v3 (Haswell) system with MSI X99S SLI PLUS motherboard, 16GB of RAM, and AMD FirePro V7900 graphics.

  • Linux kernel bug delivers corrupt TCP/IP data to Mesos, Kubernetes, Docker containers

    The Linux Kernel has a bug that causes containers that use veth devices for network routing (such as Docker on IPv6, Kubernetes, Google Container Engine, and Mesos) to not check TCP checksums. This results in applications incorrectly receiving corrupt data in a number of situations, such as with bad networking hardware. The bug dates back at least three years and is present in kernels as far back as we’ve tested. Our patch has been reviewed and accepted into the kernel, and is currently being backported to -stable releases back to 3.14 in different distributions (such as Suse, and Canonical). If you use containers in your setup, I recommend you apply this patch or deploy a kernel with this patch when it becomes available. Note: Docker’s default NAT networking is not affected and, in practice, Google Container Engine is likely protected from hardware errors by its virtualized network.

  • Performance problems

    Just over a year ago I implemented an optimization to the SPI core code in Linux that avoids some needless context switches to a worker thread in the main data path that most clients use. This was really nice, it was simple to do but saved a bunch of work for most drivers using SPI and made things noticeably faster. The code got merged in v4.0 and that was that, I kept on kicking a few more ideas for optimizations in this area around but that was that until the past month.

  • Compute Shader Code Begins Landing For Gallium3D

    Samuel Pitoiset began pushing his Gallium3D Mesa state tracker changes this morning for supporting compute shaders via the GL_ARB_compute_shader extension.

    Before getting too excited, the hardware drivers haven't yet implemented the support. It was back in December that core Mesa received its treatment for compute shader support and came with Intel's i965 driver implementing CS.

  • Libav Finally Lands VDPAU Support For Accelerated HEVC Decoding

    While FFmpeg has offered hardware-accelerated HEVC decoding using NVIDIA's VDPAU API since last summer, this support for the FFmpeg-forked libav landed just today.

    In June was when FFmpeg added support to its libavcodec for handling HEVC/H.265 video decoding via NVIDIA's Video Decode and Presentation API for Unix interface. Around that same time, developer Philip Langdale who had done the FFmpeg patch, also submitted the patch for Libav for decoding HEVC content through VDPAU where supported.

Radeon vs. Nouveau Gallium3D Driver Performance On Mesa 11.2-dev, Linux 4.5

Filed under
Graphics/Benchmarks

Here are some fresh comparison benchmarks on Linux 4.5 and Mesa 11.2 when comparing the Radeon and Nouveau (NVIDIA) open-source Linux driver performance.

Following on from the Nouveau vs. NVIDIA comparison using the latest code and the AMDGPU/Radeon vs. Proprietary Driver benchmarks on the latest code, here are some Radeon vs. Nouveau results using the Linux 4.5 kernel with Mesa 11.2 Git code for a bleeding-edge experience. The NVIDIA hardware tested for this article included the GeForce GTX 460, GTX 550 Ti, GTX 650, GTX 680, and GTX 780 Ti. With all of the NVIDIA GeForce 600/700 Kepler graphics cards, they were re-clocked to their highest power-state manually prior to testing. Unfortunately, there still isn't any working GeForce 400/500 Fermi re-clocking support with this open-source driver.

Graphics/Benchmarks

Earlier this month Hardkernel announced the ODROID-C2 as a 64-bit ARM development board that would begin shipping in March. Fortunately, you don't need to wait until next month to find out how this $40 USD 64-bit ARM development board is performing: here are some benchmarks.

Some Fresh Radeon EXA/GLAMOR 2D Acceleration Benchmarks

Filed under
Graphics/Benchmarks

It's been a while since last publishing any 2D-focused benchmarks since overall the state of Linux 2D acceleration architectures like GLAMOR and Intel's SNA have become good enough that it's no longer a frequent concern by desktop users. However, as some recently have been inquiring about updated numbers, I ran some fresh Linux 2D benchmarks on different Radeon GPUs using the open-source driver stack.

Red Hat

For those curious how the open-source Radeon Gallium3D driver has evolved over the past three years, I benchmarked every release from Fedora 18 through Fedora 23 on the same system while looking at the OpenGL Linux performance with an AMD Cypress GPU. Here is a look at the open-source Radeon driver performance evolution on Fedora Linux.

Top Android apps for your Raspberry Pi

Mostly, our tutorials are about completing a specific project and reaching a particular goal. However, this time we’re doing something a bit different. We are showing you some Android apps that you can use along with your Ras Pi. These apps aren’t tied to particular projects – you can use them whenever and as often as you like – but we think they can add something to your whole experience with the Pi. Read more

These 3 things are trying to kill Linux containers

For nearly two years, Linux containers have dominated the world of enterprise IT, and for good reason — among others, they take on issues that virtualization simply cannot within application development and computing at scale and allow for the enterprise world to truly embrace concepts like devops and microservices (the Service Oriented Architecture dream from years gone by). That sound you hear is IT vendors stampeding towards the container bandwagon, but, as with every emerging tech trend, this isn’t always a good thing, as not everyone is walking the walk, regardless of what the business might actually say.

  • GNOME Maps Is Looking Better In GNOME 3.20
    While not yet as versatile as say Google Maps, GNOME Maps for GNOME 3.20. is looking to be a nice upgrade. Maps in GNOME 3.20 is making progress with OpenStreetMap editing, expanded place bubbles, adding new places to OSM, support for printing routes, and more.
  • My Updated 3.18 Packages for GNOME Extensions
    I started releasing extension updates in 2014 due to a lot of extensions being unmaintained and seemingly break every time GNOME releases a new version of the Desktop Environment (DE). This is my third batch release post for GNOME extensions and these extension packages are for GNOME 3.18.
