色々な言語でたらい回し関数の速度を比較してみたその２

Last updated at 2024-11-21Posted at 2024-09-11

はじめに

「たらい回し関数」として知られる竹内関数を色々な言語で動かして、完了するまでの時間を測ってみました。色々な言語で計算速度を比較してみたの記事を読んだことがあり、似たようなことをやってみたいと思ってました。

これの続きです。これまでは Raspberry Pi 5 上で動かしていたのですが、動かない・動かせない言語がかなりありました、

ゆるい感じで更新を続けていく予定です。

更新

2024/11/21: Rust を 1.82.0 に、Swift を 6.0.2 に更新しました
2024/10/08: ReScript
2024/09/23: Io
2024/09/22: Seed7, Gambit
2024/09/21: COBOL

動作環境

Beelink EQ12
- CPU: Intel N100
- Memory: 16 GB

そんな速くないです。

測定内容

Tarai(x, y, z) に、初期値を x = 15, y = 5 として計算を行い、その処理時間を \time で測定します。Go 言語で 5 ~ 6 秒かかる処理になります。
