Debian Wheezy GNU/kFreeBSD: Slower Than Linux

With Debian 7.0 "Wheezy" set to be frozen soon, I took the opportunity to run some new benchmarks of Debian GNU/kFreeBSD, the Debian OS variant using the FreeBSD kernel rather than Linux, to compare it to Debian GNU/Linux as well as Ubuntu Linux and PC-BSD/FreeBSD 9.0.

Ubuntu 8.04.4 LTS, 12.04 LTS, 12.10 On An Old Laptop

Last week I shared how the open-source R500 driver can compete with the legacy Catalyst Linux driver on an old Intel laptop with ATI graphics, but how has the performance for other areas of the system changed with the latest Ubuntu Linux code? In this article are benchmarks from other areas of this Core Duo laptop when running Ubuntu 8.04.4 LTS, Ubuntu 12.04 LTS, and then a recent development snapshot of Ubuntu 12.10.

Ubuntu 12.04 LTS ARMv7 Linux Performance Gains

Earlier in the Ubuntu 12.04 LTS "Precise Pangolin" development cycle I noted some performance improvements happening on the ARM side, particularly for Texas Instruments OMAP4. Namely, Ubuntu 12.04 was ARMing up for better performance with ARM hard-float support and the performance becoming more compelling for the PandaBoard ES hardware with proper cpufreq support. In this article is a comparison of the Ubuntu 11.10 and Ubuntu 12.04 ARM performance.

Microsoft Windows 8: Mostly A Crap Wreck

For the past few days I have been trying out the Microsoft Windows 8 Consumer Preview. For the most part, I would call Windows 8 a crap wreck, but it is not without a few advantages over Linux.

Ubuntu 12.04 vs. Windows 7: Intel Sandy/Ivy Bridge Loses On Linux

Here's a comparison of the Ubuntu 12.04 LTS versus Microsoft Windows 7 performance when it comes to using Intel Sandy Bridge and Ivy Bridge processors with integrated graphics. While the Sandy Bridge graphics performance was once faster when it came to OpenGL with the open-source Linux driver, that's no longer the case. The Linux OpenGL performance for both Sandy Bridge and Ivy Bridge hardware is now slower in most GL workloads than Intel's Windows 7 x64 driver.
