「Raspberry Pi 2」を UnixBench でベンチマークした。
手順とログを貼っておきたいので、長くなるので結論から書くと「Raspberry Pi 2」のスコアは「440.9」でした。
「Raspberry Pi 1 Model B」のスコアは「75.9」だったので、「約6倍」の実行速度はその通りだった。（440.9 / 75.9 = 約 5.8）
以下、UnixBench の実行手順と実行結果、各 Raspberry Pi のスペックなど。

$ tar zxvf UnixBench5.1.3.tgz実行
$ cd UnixBench/
$ ./Run実行時のエラーについて
UnixBench 実行すると下記のエラーがでるけど、「locale」って書いてあるので地域や言語の設定が何か足りないんだと思う。「Raspbian」の初期設定時に地域と言語を日本に変更したのでその関係かなぁ。まぁ実行自体はできているのでとりあえあず無視する。
locale: Cannot set LC_CTYPE to default locale: No such file or directory
locale: Cannot set LC_MESSAGES to default locale: No such file or directory
locale: Cannot set LC_ALL to default locale: No such file or directory
locale: Cannot set LC_CTYPE to default locale: No such file or directory
locale: Cannot set LC_MESSAGES to default locale: No such file or directory
locale: Cannot set LC_ALL to default locale: No such file or directoryUnixBench の実行結果
いろいろ出力されるけど、最後の「System Benchmarks Index Score」が最終的なスコアだと思われる。
Raspberry Pi 2 のベンチマーク結果
「Raspberry Pi 2」の「System Benchmarks Index Score」は「440.9」。
