Действительно, регресс 2.6.18-alt* -> ... -> 2.6.30-alt* есть
по тестам unixbench (см. attachment).
Проверялось в qemu, на реальной машине соотношение результатов может
быть другим.
btw, "vanilla" 2.6.29.6 в qemu работает на глаз заметно шустрее
2.6*-alt*, по тестам производительность в разы выше, не разбирался;
возможно, с калибровкой времени непорядок.
WBR,
Oleg.
