ExecutorServiceの最大プールサイズを考える(Java) †
概要 †「N個のデータの塊を 何個のスレッドで処理するのが一番効率が良いのか」を コア数との関係を考慮しながら 確認する。 今回、検証に使用したプログラムの概要は以下の通り。
 結果 †先に結果を書いてしまう。 今回のような単純なMapインスタンスの生成を繰り返すようなプログラムの場合は、 良くないのはスレッド数 ≧ コア数の時 で、スループットもヒープ効率もかなり悪い結果となった。 恐らく、コア数以上のプール(スレッド)数で処理した場合、コンテキストスイッチが多数発生する事になる為、 ただし、ヒープの割り当て方によっては今回の結果も大きく変わる可能性がある事には注意したい。 結果(補足) †尚、Executors.newCachedThreadPool 及び Executors.newWorkStealingPool で同様の動作確認も行ってみたが、 またメインスレッドの起動時にスレッドプールを生成し、以降はそれを使い回す方式も確認してみたが、 プロジェクト作成 †確認用のプロジェクトは以下の通り作成した。 build.gradle †plugins {
