ctsTraffic でパフォーマンス測定

ctsTraffic はマイクロソフトのドキュメントで登場するネットワーク ツールです。

Linuxではiperfなどがあります。

これはWindows 用のツールです。

バージョン2.0.3.0を利用します。arm64、X64、X86が用意されています。

自分の環境に合わせてダウンロードします。

必用なのctsTraffic.exe のみです。クライアント側とサーバー側にダウンロードしておきます。

それぞれコマンドを打つ準備をします。サーバー側はクライアントを待って開始してくれるツールではありません。

サーバー

ctsTraffic.exe -listen:* -consoleverbosity:1

クライアント

ctsTraffic.exe -target:{サーバーIP} -consoleverbosity:1

これは一番単純な利用方法です。

PS C:\Users\azureuser> C:\Users\azureuser\Desktop\ctsTraffic.exe -listen:* -consoleverbosity:1

  Total Bytes Recv : 296
  Total Bytes Sent : 999555072
  Total Time : 55513 ms.

ここからスループットを計算します。

  Total Bytes Recv : 989665266
  Total Bytes Sent : 296
  Total Time : 64437 ms.

( 989665266 / 64437 ) * 8 = 約122Mbps

家の回線が最大で350Mbpsなのでそのぐらいでしょう。

あと注意事項としてクラウド側からどこかに計測するとトラフィックの料金がかかるので気を付けてください。
