попробовал, ядро действительно немного быстрее (возможно те самые 11%
или больше).
собирал только необходимые мне модули, (сделал lsmod и вспомнил
конфигурацию машины) и вот результаты, особенно заметна разница в file
read/write в области с малом размером буфера, не относящиеся к file
тесты я вырезал (то есть обычные конфигурационные файлы):
так что мое предложение - забить на performance до выхода linux-2.6.12
