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。
ctsTraffic は、詳細なパフォーマンスと信頼性の分析を提供する、高度にスケーラブルなクライアント/サーバー ネットワーキング 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。
