...Microsoft Research has released part of a report on the "Singularity" kernel they've been working on as part of their planned shift to network computing. The report includes some performance comparisons that show Singularity beating everything else on a 1.8Ghz AMD Athlon-based machine.

What's noteworthy about it is that Microsoft compared Singularity to FreeBSD and Linux as well as Windows/XP - and almost every result shows Windows losing to the two Unix variants.
