Добрый день,

После обновлении ядра 2.6.18 -> 2.6.30 на вчерашнем  Sisyphus
обнаружилась потеря производительности в тестах unixbench-5.1.2.

Тест сделан после сравнения на глаз "шустрости" школьных ALT 4.0.* и
ALT 5.0.0beta, последний был субъективно медленнее первого при всех
прочих равных.

Таблица с результатами unixbench прилагается.

WBR,
Oleg.
