Linux 2.6.23-rc2 Kernel Performance

While the Linux 2.6.23 kernel is only weeks into development, it's already generated quite a bit of attention. From the merging of the Completely Fair Scheduler (CFS) to the -rc2 kernel being "the new -rc1", the Linux 2.6.23 kernel is certainly in store for being an ornate release. Adding to this attention has been a stable user-space driver API and virtualization improvements (KVM, Xen, and LGuest). With all of this activity surrounding the Linux 2.6.23 kernel we've decided to conduct a handful of benchmarks comparing the Linux 2.6.20, 2.6.21, 2.6.22, and 2.6.23 kernel releases so far.

In this comparison we had used the latest kernel versions in the Linux 2.6.20 through 2.6.23 branches at the time of testing, which is the 2.6.20.15, 2.6.21.7, 2.6.22.1, and 2.6.23-rc2 kernels. The hardware used for all of the kernel tests were two Intel Xeon LV 2.00GHz dual-core processors, Tyan Tiger i7520SD (S5365) motherboard, 1GB of DDR2-400 ECC Registered memory, NVIDIA GeForce FX 5200 PCI 128MB graphics card, and Western Digital 160GB Serial ATA hard drive. The Linux distribution used was Fedora 7 with GCC 4.1.2 and X server 1.3. All kernels used in testing were built from source with no external patches applied and the same basic configuration. Benchmarks had consisted of LAME compilation, LAME encoding, timed disk reads, Gzip compression, and RAMspeed with our standard Linux benchmarking procedures. No graphics tests were conducted due to the system hardware used.

Wireless-enabled i.MX6 SBC offers remote IoT management

Eurotech’s “CPU-351-13″ SBC runs Linux on Freescale’s i.MX6 SoC, and offers ZigBee, GPS, extended temperature operation, remote IoT management, and more. Eurotech has been promoting the concept of managed Internet of Things devices long before “IoT” became the latest craze. The Yocto Linux ready CPU-351-13 single board computer is the latest of its embedded boards that can be remote controlled using its Everyware Software Framework (ESF) and Everyware Cloud Client. Other Everyware-enabled products from Eurotech include last year’s Intel Atom E3800 based Catalyst BT module. Read more

Leftovers: Software

  • gimp-paint-studio addon soon on Gnome Software Center
    Image speaks itself. gimp-paint-studio package just got an metainfo needed for Gnome Software Center as add-on for Gimp based on related Richard Hughes' blog. The updated package will be shortly available in Rawhide and also in Fedora 21 updates-testing repository. It will not be included for Fedora 20 due to the preview release of Gnome Software lacking addons support. Next step will be contacting upstream adding that metainfo. Hopefully other add-ons maintainers for applications such as Inkscape and Blender will do the same to bring a richful experiences to users.
  • CD Audio Grabbers - Graphical Based
    CD audio grabbers are designed to extract ("rip") the raw digital audio (in a format commonly called CDDA) from a compact disc to a file or other output. This type of software enables a user to encode the digital audio into a variety of formats, and download and upload disc info from freedb, an internet compact disc database.
