bc(1)で性能測定

はじめに

bytebenchより手軽。OSのほとんどベースシステムだけで動く。たぶんCPUに強く依存しOSにはあまり影響されないと思うがコンパイラには強く依存するような気もする。

方法

πの小数点以下2000桁計算時間 

    time sh -c 'echo "scale=2000; 4*a(1)" | bc -l' > /dev/null

eの小数点以下2000桁計算時間 

    time sh -c 'echo "scale=2000; e(1)" | bc -l' > /dev/null

注: GNU bcではない場合、scale=2000は不可能なことが多いようだ

結果

CPU/Machine OS π e
