【Unix】unixbenchの備忘録

最終更新日:2019/05/19

先日購入したラズパイ3B+でベンチマークを動かして見たときのまとめです。
尚、使用したベンチマークですが、unixbenchを使用してみました。
今度PC(Ubuntu)でもやってみようと思うので、その為の備忘録です。

1.検証対象



  ①Raspberry Pi 3B+(以下ラズパイ3B+)
   CPU:
Broadcom BCM2837B0, Cortex-A53 (ARMv8)1.4GHz
   MEM:1GB
   OS :raspberrypi 4.14.98-v7+
   備考 :MicroSDは"SAMSUNG EVO 32GB Class10 UHS-I"

  ※今後追加予定


2.unixbenchの導入・実行手順



以下のコマンドを順次実行する
sudo apt install git
git clone https://github.com/kdlucas/byte-unixbench
cd byte-unixbench/UnixBench
./Run

○ベンチ結果まとめ
 ・スコア :1 parallel(308.1)/4 parallel(745.3)
 ・実行時間:1 parallel(28分09秒)/4 parallel(28分22秒)/合計(56分31秒)
 ・最高温度:4 parallelの"4 x Shell Scripts (8 concurrent) "中にtemp=80.1'Cを記録
  ※室温24度
 ・特記事項:実行中に幾つかスプリプトのエラーが出ていた


とりあえず次はジャンクPCのVersaproでも走らせてみる予定です。
