/dev/sda:
Timing cached reads: 2216 MB in 2.00 seconds = 1108.00 MB/sec
Timing buffered disk reads: 6 MB in 3.02 seconds = 1.99 MB/sec
Почему трансфер такой медленный? И можно ли добиться увеличения скорости
работы винта?
Спасибо!

Вы так ни разу не сказали, что это за диск, а также дебиановское
ядро или альтовское. Ну или не видел как минимум.
