    We tested on i386 as well at the time, and it looked like a tiny
    improvement. But doing the statistics, it was in the noise.
    I have no numbers for x86_64 or ppc64.

    If you have reason to believe that there could be regressions, we
    should indeed do the benchmarks.

    Sidenote: The patches 1 -- 2b alone still make sense, so I would
    vote not for delaying their inclusion until we can collect numbers
    for all arches we care about to take a decision on patch 3.
