Ubuntu 12.10 KVM Virtualization Comparison

For kicking off a new week of Linux benchmarks, here are some results of a high-end Intel Extreme Edition workstation when comparing the bare metal host and KVM virtualization performance between Ubuntu 12.10 and the earlier Ubuntu 12.04.1 LTS release and then the RHEL-based CentOS 6.3.

AMD Catalyst: Ubuntu 12.10 vs. Windows 7

For those wondering about the performance of Ubuntu Linux 12.10 versus Microsoft Windows 7 when using the same system and the Catalyst graphics driver, here are new Phoronix benchmarks of an AMD Radeon HD 6870 graphics card when running a variety of OpenGL workloads from Ubuntu 12.10, Kubuntu 12.10 (the KDE desktop version of Ubuntu 12.10 to avoid the Unity desktop overhead), and Microsoft Windows 7 Professional x64.

Ubuntu 12.10: 32-bit vs. 64-bit Linux Performance

In past years on Phoronix there has been no shortage of 32-bit vs. 64-bit Linux benchmarks. Assuming you don't have a limited amount of RAM and under memory pressure, 64-bit distributions tend to be much faster than the 32-bit versions. However, some Linux users still often wonder whether they should use the 32-bit or 64-bit version of their distribution even when on 64-bit hardware. So with that said, here's some more 32-bit vs. 64-bit benchmarks of Ubuntu 12.10 with the Linux 3.5 kernel.

Preview Of Ubuntu 12.04 LTS vs. Ubuntu 12.10 Performance

When Ubuntu 12.10 "Quantal Quetzal" is officially released there will be more Ubuntu 12.10 performance figures to publish beyond what's already been benchmarked. In this article are a preview of some Intel performance figures comparing an updated Ubuntu 12.04.1 LTS installation to Ubuntu 12.10 with its near-final packages as of this week.

Early Benchmarks Of The Linux 3.7 Kernel

While the Linux 3.7-rc1 kernel has not even been released yet, most of the feature pulls have now made their way into the mainline Linux kernel tree. Here are some of the first benchmarks of the Linux 3.7 kernel to see if anything has changed for the Intel x86_64 Linux performance with this very exciting kernel.

Unity 6.8 Doesn't Change Much For Performance

While LLVMpipe may be a different story, when using hardware-accelerated graphics drivers with the recently released Unity 6.8 desktop, the performance doesn't change much. For at least one driver, there's even a new OpenGL performance regression under certain workloads. Here's some test results of Unity 6.6 vs. Unity 6.8 on the Radeon and Nouveau drivers.

Unity 6.6: Still Regressing On Performance?

With the recent release of the Unity 6.6 desktop for Ubuntu 12.10 Beta 2, benchmarks were done to see how the OpenGL gaming performance compares to that of Unity 6.4 from the earlier beta state of the Quantal Quetzal, plus the respective Compiz versions. At least for Intel Ivy Bridge graphics under some workloads, it looks like the Unity/Compiz updates are slowing down the GL performance even further.

Intel Atom D525: Ubuntu 10.10 To 12.10

In this article are benchmarks of ALUSA's Intel Atom Desktop that packs an Intel Atom D525 processor with Intel GMA 3150 graphics, 2GB of RAM, and a 500GB SATA disk. The benchmarks are from Ubuntu 10.10, Ubuntu 12.04.1 LTS, and an Ubuntu 12.10 development snapshot to see how the performance has evolved since this Intel Atom CPU was introduced two years ago.
