(yet another) UnixBench on Bash on Ubuntu on Windows

[fujieda](http://qiita.com/fujieda)さんの「[UnixBench on Bash on Ubuntu on Windows](http://qiita.com/fujieda/items/b905d2448b8a0db47095)」を見て自分の環境(Core i5-2410M、メモリ8GB、ハイブリッドHDD)でもやってみた。

# Build 16251 (16251.rs3_release.170721-2122)

このビルドからWindows Subsystems for Linuxのベータが取れました。UnixBenchはいつものようにエラーが出たので`-i 3`オプション付きで実行して、スコアは185.1。また少し回復してますが、200台に戻すことはなさそうですね。

# Build 16188 (16188.rs_prerelease.170430-1928)

Creator's Update後のInsider Previewです。`-i 5`オプション付きで実行して、スコアは166.5。
WSLをインストールし直したのが良かったのかわからないが、少し回復。とはいえ、初期のスコアには到底届かないですね。いろいろ実装するとやっぱり遅くなってしまうのでしょう。

WSLを削除して再セットアップして試した。テストも落ちなくなったしスコアも少し上がった。ぐぬぬ。これまでのテストスコアの信頼度が低いことがわかった。

4並列のスコアは228.6。

# Build 14936 (14936.rs_prerelease.160923-1700)

このビルドから正式にXenialに対応したとのことで、do-release-upgradeを実行してバージョンを上げました。

でもやはりベンチ途中で落ちたので、繰り返し回数を4回にして (-i 4オプションを与えて) 実行してます。

4並列のスコアは222.5。倍精度浮動小数点演算が大きく下がり、整数・文字列演算も下がった影響でしょうか。

# Build 14931 (14931.rs_prerelease.160916-1700)

Build 14926と同じくエラーで落ちたので、繰り返し回数を5回にして (-i 5オプションを与えて)実行しました。

それが影響したのかしないのか、4並列のスコアは235.1。ファイルコピーが遅くなってスコアの足を引っ張った感じ。

#Cygwin

4並列で332.8。ファイルシステムはデフォルトのまま(noaclはつけていない)。

Bash on Ubuntu on WindowsとCygwinとは用途（というか目的）が違うので、Cygwinより遅いから使わないとか、Cygwinより速いから乗り換える、みたいなことはお勧めしない。
