AWS に 100Gbps の新インスタンス出たそうなので・・・
自腹で試してみるって企画です。
2台立ち上げると、1時間で $7.76 が吹き飛びます。
Conoha の安い VPS が一か月使えますね。。。
c5n ってどんなインスタンス？
こんなインスタンスですね。
| Instance Name | vCPUs | RAM | EBS Bandwidth | Network Bandwidth | Hourly Price |
|---|---|---|---|---|---|
| c5n.large | 2 | 5.25 GiB | Up to 3.5 Gbps | Up to 25 Gbps | 0.108USD/h |
| c5n.xlarge | 4 | 10.5 GiB | Up to 3.5 Gbps | Up to 25 Gbps | 0.216USD/h |
| c5n.2xlarge | 8 | 21 GiB | Up to 3.5 Gbps | Up to 25 Gbps | 0.432USD/h |
| c5n.4xlarge | 16 | 42 GiB | 3.5 Gbps | Up to 25 Gbps | 0.864USD/h |
| c5n.9xlarge | 36 | 96 GiB | 7 Gbps | 50 Gbps | 1.944USD/h |
| c5n.18xlarge | 72 | 192 GiB | 14 Gbps | 100 Gbps | 3.888USD/h |
では、立ち上げ。
東京リージョンにはまだ来てないので、バージニアでいってみます。
ドキドキです（そんなピュアな年齢でもない・・・）
セキュリティとかは相互通信できる程度に開けて、後は、デフォルト使う感じで適当です。
ちょっと見てみる
72個も CPU 並んでるの初めて見ましたよ。
総計、144個ですよｗ
壮観です。
メモリも桁入りきってないですね。
ちなみに free 叩くとこんな感じです。
# free
total used free shared buff/cache available
Mem: 193694504 489280 192512544 640 692680 191945800
Swap: 0 0 0
では、速度測っていきましょう
おなじみの iperf 使っていきます。
一台をサーバモード（iperf -s）で上げて、もう一台をクライアントでいきます。
一応、両方からやってみたので、どちらも載せてみます。

あれ？ 100Gbps 回線といいつつ、実態は 9.45Gbps くらいしか出てないですね・・・
一応、1秒単位とかでないデフォルトの10秒のやつでもやって結果は同じでした。
確かに、秒間 1Gバイトが飛んでるってすごいですけど。
おまけで、スピードテストもやってみた

5Gbps 近く出ているので、計測サーバ側も相当速いやつですね。。。
まとめ
なんか、100Gbps というので期待してみたのですが、実態的には 1/10 くらいなんでしょうかね。
そのうち時間とお金の余裕があるときにまた試したいと思います。
まぁ、それでも速いことには変わりないので、潤沢にお金ある人は使ってみるといいかもしれません。
そんな回線でも、日本から SSH 接続すると、もっさり感はあるので、経路の問題は難しいですね。
