gOS and Linux Mint are two of the many Linux distributions based upon Ubuntu, but they provide their own spin of things. We had a question though from a reader asking whether the performance of these Ubuntu derivatives is vastly different from Ubuntu itself. With that inquiry, we have run a couple benchmarks comparing the performance of Ubuntu 8.10, gOS 3.1, and Linux Mint 6.
For this testing we used a Lenovo ThinkPad T400 notebook with an Intel Core 2 Duo T9600 processor at 2.80GHz, 160GB ST9160823AS SATA HDD, Intel GMA 4500 Mobile graphics, and 1440 x 900 display. As to the key packages found in each of the three distributions being tested, Ubuntu 8.10 uses the Linux 2.6.27 kernel, GNOME 2.24, X Server 1.5.2, xf86-video-intel 2.4.1, Mesa 7.2, and GCC 4.3.2. While gOS 3.1 Gadgets is a new distribution, it's still shipping with packages based on Ubuntu 8.04. gOS 3.1 uses the Linux 2.6.24 kernel, GNOME 2.22.2, X Server 18.104.22.168, xf86-video-intel 2.2.1, Mesa 7.0.3-rc2, and GCC 4.2.4. Linux Mint 6 is following the Ubuntu 8.10 package set and it features the same key versions as what is found in Ubuntu 8.10. All distributions were installed with their default options and during testing each distribution was ran with everything being at their defaults.
