Benchmarking the very earliest publicly-available code for Google Chrome OS seems destined to only highlight the platform's early stage of development, especially when you throw rivals such as Moblin 2.1, Ubuntu Netbook Remix 9.10, Fedora 12 and openSUSE 11.2 into the mixture. Still, that's just what Phoronix have done, and unsurprisingly the new Google netbook OS came in last position.
Phoronix used a Samsung NC10 as their test mule, and then put the various netbook and desktop distros through a number of challenges. That included H.264 video playback, OpenArena, LZMA compression, 7-Zip compression, IOzone, PostMark, dcraw, Ogg Encoding, FFmpeg and x264 video encoding, some of which you could readily argue might not be the usual netbook fare.
Still, they went on to look at CPU use and battery life, eventually crowning Ubuntu Netbook Remix 9.10 as the best netbook distro thanks to its top runtime and minimal demands on processor and memory. The test results may not be too surprising, at least in terms of Google Chrome OS, but it's an interesting read from an open-source OS perspective.
