Linux "In recent weeks and months there has been quite a bit of work towards improving the responsiveness of the Linux desktop with some very significant milestones building up recently and new patches continuing to come. This work is greatly improving the experience of the Linux desktop when the computer is withstanding a great deal of CPU load and memory strain. Fortunately, the exciting improvements are far from over. There is a new patch that has not yet been merged but has undergone a few revisions over the past several weeks and it is quite small - just over 200 lines of code - but it does wonders for the Linux desktop."

From the article you linked:

The Tsubame team ran their Top 500 benchmarking tests on both Linux and Windows, and the difference in performance was less than 5% but Linux did come out on top, Hilf says. Hilf attributes Linux's slim victory to the Tokyo researchers running the Linux tests on a slightly larger number of nodes. I'm not sure why the tests were run on a different number of nodes, but I will be interviewing Matsuoka at this week's SC10 supercomputing conference in New Orleans and will attempt to find out.

I think I know why. It's because on a machine that probably needs millions of dollars just to flip the switch, there are more important things than just nailing a benchmark.

I don't know if Linux is more efficient than Windows in HPC, but the article you linked doesn't say much either.
