画像は前回の使い回し
そういえばNanoPi NEOの性能はどの程度なものだろうか、ということでベンチマーク。
使ったのはUnixBench。
armbianは基本的なものは一通り揃っているのでUnixBench以外は特に事前に準備する必要は無し。
$ wget https://storage.googleapis.com/google-code-archive-downloads/v2/code.google.com/byte-unixbench/UnixBench5.1.3.tgz $ tar -zxvf UnixBench5.1.3.tgz $ cd ./UnixBench $ ./Run -c 1 -c 4
UnixBenchの実行は ./Run でも良いが、今回は4コアのCPUなので単独実行の-c 1と4パラレル実行の-c 4を追加指定している。
なお、UnixBenchは計測に時間がかかる。NanoPi NEOでは大戸屋で食事して歯を磨いてトイレに行くくらいは余裕。

System Benchmarks Index Score 429.0
1パラレル(つまりシングル、オプション無しの./Runと同じ)でIndex Scoreが164.1、4パラレルで429.0というのは他所の人が掲載しているUnixBenchの結果で見る限りはRaspberryPi2 ModelBに数字上は僅かに及ばないものの事実上「ほぼ匹敵」といってよいレベル。僅か$7.99という最低グレードのNanoPi NEOがこれだけの結果を出すとは正直意外。違った、メモリ512MBモデルは$9.99だった。
NanoPi NEOのUnixBenchでこちらのページでは4パラレルが342.6と書かれているが約25%も結果が違うのは何でだろう。個々の結果も全然違うっぽいけど・・
メモリ搭載量が違うモデルだからとか？
ところで、UnixBenchでは何故かCPUの認識が正しくなくて「0 CPUs in system;」という表示が出ている。

Serialの*の部分は伏せている。
なんとなく4コアあるらしげな表示ではあるが情報がいろいろ足りないように思う。これが原因でUnixBenchでもCPUの情報が変なのかな。
