- 更新履歴
更新履歴
- 2023/11/29 初版
- 2023/11/30 テスト環境６を追加
はじめに
このドキュメントは．Microsoftが無償で提供するnttcp.exeコマンドを使って，ネットワークパフォーマンスを計測し，その結果 を掲載する．EXEの入手
- 以下のURLから入手する．
- https://github.com/microsoft/ntttcp/releases
- 今回使ったのは，v5.39
コマンドオプションの説明
- 以前はZIP形式で配布されていてドキュメントもついていた様だけど，Githubで配布されている現在はドキュメントが無いので
ネットで調べて転載．
-s 送信側指定
-r 受信側指定
-m マッピング、 <使用スレッド数>,<スレッド番号>,<受信IPアドレス> を定義
-t 計測時間
-ns windows側で、Linuxと通信する際
-N Linux側で、Windowsと通信する際
テスト環境１・・・5GHzのWi-Fi環境で計測
- 最初のテスト環境は，特に何も設定を変更してない現在利用しているネットワークを利用．
- 次のような状態．
- RTX1200はDMZ付きの３ネットワークセグメント構成で，配下にWi-Fi 5相当となるアクセスポイントNETGEAR WAC510に接続した2台のWindowsパソコンを利用．
- OSはWindows 10 Proで，執筆時点（2023/11/29）のWindows Updateは全て適用した状態．
- テスト用のコマンドは次のオプションを指定．
●CF-RZ6を送信側とする
C:\Users\ujpadmin\Desktop\ntttcp.exe -s -m 2,*,192.168.20.154
-t 10
●Endeavoar TN20を受信側とする
C:\Users\ujpadmin\Desktop\ntttcp.exe -r -m 2,*,192.168.20.154 -t
10
- コマンドを実行すると，環境によっては次のようなダイアログが表示される．
- アクセス許可をする．
- まずは送信側のテスト結果．

- 受信側の Throughput(MB/s)は15.329MB/sなので122.632Mbit/s．
テスト環境１・・・5GHzのWi- Fi環境で計測したサマリ
- 機器の仕様は次のとおり．
- RTX1200 最大1.0Gbit/s フィルタなし．
- NETGEAR WAC510は，2.4GHzと5GHzのスループットは合計で1.3Gbps
- 送受信が共に123Mbps程度．この状態が遅いのか否かは不明だが，体感でネットワークが遅いと感じることはない．
テスト環境２・・・工場出荷時設定のRTX1200のLAN1で計測
- テスト１の環境だと，RTX1200にフィルタ設定が入っているのと，Wi-Fiを経由なので，性能劣化が考えられる．
- 今回のテストでは最小限環境影響がとして，RTX1200をリセットし，デフォルトの最小限設定（DHCP設定）が入っているだけの 環境でテストしてみた．
- 図解すると次の様な状態．
- まずは痩身側のテスト結果．

- 112.258MB/sなので898.064Mbit/s．
テスト環境２・・・工場出荷時設定の RTX1200のLAN1で計測のサマリ
- RTX1200の性能が最大1.0Gbit/sなので，900Mbit/sの性能が出たのは良好．
テスト環境３・・・LINKSYS LGS105-JPスイッチを使って
- テスト環境２に，L2スイッチを追加してRTX1200の性能影響を受けない状態で計測してみる．
- 利用したL2スイッチはLINKSYSのLGS105-JPで，バッファメモリは無しでスイッチングファブリックは10Gbpsのも
の．

- 112.063MB/sで896.504Mbit/s
テスト環境３・・・LINKSYS LGS105-JPスイッチを使ってのサマリ
- RTX1200直結より1%程度劣化．大きな差はない模様．
テスト環境４・・・ バッファロー LSW3-GT-5NSスイッチを使って
- テスト環境３で利用したL2スイッチはキャッシュがない安いスイッチだったので，うちにあるもう少し性能の良いスイッチでテストする ことにした．
- この機種は，バッファメモリ104KByteでスイッチングファブリック12Gbps．
- 送信テスト．

テスト環境４・・・ バッファロー LSW3-GT-5NSスイッチを使って
- テスト環境３とテスト環境４ではL２スイッチのバッファの有無の違いがあったが，こういう１対１でのパフォーマンステストでは影響，
つまりバッファメモリの効果は無いのかもしれない．
テスト環境５・・・ Panasonic Switch-M8eG(PN28080)スイッチを使って
- 家庭用製品と業務用製品の違いがどれくらいあるのかという切り口で確認．
- この機種はバッファメモリ512KBでスイッチングファブリックは18Gbpsという仕様．
- 送信テスト．

- 送信は112.584MB/sなので900.672Mbit/s
- 受信は112.284MB/sなので898.272Mbit/s
テスト環境５・・・ Panasonic Switch-M8eG(PN28080)スイッチを使ってのサマリ
- ここまででキャッシュ無し，キャッシあり(104KByte)，キャッシあり(512KByte)の３種類のスイッチを試したが，差 が出ている部分としては送信スピードがキャッシュがある方が速いという結果が出ている．
テスト環境６・・・ テスト環境１から無線AP WAC510を回避して接続した場合
- テスト環境１の結果，15.514MB/s（124.112Mbit/s）と他の10分の1の性能だったので，原因が無線APの NETGEAR WAC510なのかRTX1200のフィルタ負荷なのかを切り分けるため，無線LANを取った状態で検証．
- 図解しながら気づいたけど，よく考えたら中央にあるスイッチ間で通信するから，テスト結果としてはテスト環境５と変わらない
ね．RTX1200(フィルタあり)に通信が行かないので性能に関係ないし．
- 送信結果．
