    Default Linux 3.4 Kernel Benchmarks

    Phoronix: Linux 3.4 Kernel Benchmarks

    Here's a look at the performance of the Linux 3.4 kernel, which was recently released, compared to all major kernel releases going back to Linux 2.6.39. Multiple kernel sub-systems are being compared in this round of Intel Linux benchmarking.

    What about energy-consumption-when-idle?

    In other series you addressed the energy consumption issue under linux. It would be nice to see how well it scales across different kernel revisions, and if possible throw a Windows 7 and Mac OS X in the mix for us to get the full picture, i.e. If I throw a linux distro on my [note/net/ultra/mac]book, will I get equal or better battery life than other mainstream OSes?

    I remember reading that Ubuntu enabled some extra power saving optimisation in 12.04. I'd be interested to see it compared with Fedora and CentOS. (maybe a bit of stock Debian too)

    Keep up the good work Michael, you do a good job.

    Default and the winner is...

    3.4 git on the test selection!

    "2.6.39" "3.0" "3.1" "3.2" "3.3" "3.4 Git"
    100.0 102.8 102.1 101.1 103.1 104.2

    By about 4.2% over 2.6.39 and about 1.1% over 3.3.
    (Note, also includes some graphics tests)

    Congratulations!)

    Code:

    Why does the compile bench becnchmark show the 3.0 kernel as 2x faster than the others with no mention of it?

    This? http://www.phoronix.com/scan.php?pag...tem&px=MTA0OTU
    I think at least some of these optimizations (e.g. RC6) are enabled by default in 3.4.
