ディスク性能

• https://thr3a.hatenablog.com/entry/20180804/1533378243

以下みたいな感じで出る

Seq-Read 98.605
Seq-Write 95.411
Rand-Read-512K 101.813
Rand-Write-512K 0
Rand-Read-4K 961.114
Rand-Write-4K 1.252
Rand-Read-4K-QD32 946.368
Rand-Write-4K-QD32 0
isucon@team015-001:~$

読みづらい

単位はMB/s

一旦ここだけ見とくと良い

Seq-Read 98.605
Seq-Write 95.411

注意点は実行するといい感じにディスクを使うのでディスク容量がいっぱいになる

ディスク性能こっちのほうが見やすい
