Seekwatcher generates graphs from blktrace runs to help visualize IO patterns and performance. It can plot multiple blktrace runs together, making it easy to compare the differences between different benchmark runs. Seekwatcher なんとこんな素晴らしいものがあるとは。ありがとう、Chris Mason。 [root@yazekats-linux work]# which seekwatcher /usr/bin/seekwatcher お、すでに入ってる。グラフできるかな？ [root@yazekats-linux work]# seekwatcher -t sda.
