Я новый пользователь IOzone, когда я запускаю IOzone с командой: ./iozone -i 0 -i 1 -t 2 -T
, он генерирует следующий результат (частично):
Command line used: ./iozone -i 0 -i 1 -t 2 -T
Output is in Kbytes/sec

Я запутался в значении «пропускная способность» и «Min xfer», кто-то может мне помочь?Кстати, почему пропускная способность, видимая от детей и родителей, отличается?Спасибо!
