3.14159265..なπの日の夜、スイッチサイエンスさんにいきなり電話をしまして、電波法に抵触しない適法上でのテストを行うためにシールドボックスをお借りしてベンチマークを実施しました。外に対してはUSBのポートがでていて、このポートと内部にあるUSBがブリッジのような形になっており、このUSBからRaspberry Pi 3B+と接続ができるようになっております。
で実際のテストはといえば中に閉じ込めて行わねばいけなくて、外部のインターネットと直接接続できる何かがでているわけでもないため、テストはおなじみのUnixbenchぐらいがやっとなのが事実です。なので、いつもながらおなじみで申し訳ないのですが、Unixbenchをとってみました。

ほんと、技適の問題でおおっぴらに電源をいれられないのは口惜しい限りですが、ご参考ください。また深夜だというのに押しかけでシールドボックスをお貸しいただきましたスイッチサイエンス様に御礼申し上げます。
