+# Benchmark
+
+## dd-benchmark
+
+書き込み, 読み込みの測定には[dd-benchmark](https://romanrm.net/dd-benchmark)を使用する。最近では[fio](https://github.com/axboe/fio)がお勧め。
+
+* 下記のコマンドで測定を行う。
+```sh
+# 書き込み
+dd if=/dev/zero of=benchmark bs=64K count=64K conv=fdatasync
+
+# 読み込み
+dd if=benchmark of=/dev/null
+```
+
+* `conv=fdatasync`が最も普段の動作に近いらしい。
+>This tells dd to require a complete “sync” once, right before it exits. So it commits the whole 256 MB of data, then tells the operating system: “OK, now ensure this is completely on disk”, only then measures the total time it took to do all that and calculates the benchmark result.
+
+### 測定用のshell
+
+ベンチでは, 128MB, 256MB, 512MB, 1GB, 2GB, 4GBの書き込み, 読み込み速度を測定する。測定用のshellは下のやつを利用する。
+
+```sh
+#!/bin/sh
+
+for c in 2 4 8 16 32 64
+do
+    echo "Write"
+    dd if=/dev/zero of=benchmark bs=64K count=$c"K" conv=fdatasync
+
+    echo "Read"
+    dd if=benchmark of=/dev/null
+    
+    rm benchmark
+done
+```
