Windows 10 Insider PreviewのBash on Ubuntu on WindowsでUnixBenchを取ってみた。
Build 14936
14393で下がったスコアが14376並みに戻ったというところ。ベンチマークの結果に大きな影響を与えるものではないが、Ubuntuのバージョンを16.04に上げてUnixBenchをコンパイルし直してから計測した。

後述する同じVMで動かしたCygwinの結果と比べて、execが8倍くらい速いのでシェルスクリプトの実行速度で大きな差が付いている。Cygwinが最も苦手とするProcess Creation (fork)で2倍しか差がないので、forkはそれほど速くない。ファイルシステムはCygwinと比べてやや遅い。この結果は/rootで取ったが、/mnt/cの下で取ると少し早いもののCygwinに及ばない。
