Есть задача обработки большого массива, который периодически обновляется.... Всем добрый день!

Есть задача обработки большого массива, который периодически обновляется.
Чтобы ускорить обработку, я разделил массив пополам и запустил обработку в 2 потока. Т.е. создаю 2 потока, а по завершении обработки потоки закрываю (join).
Но каждый раз создавать потоки - не очень эффективно, т.к. это требует ресурсов.
Правильно бы было создать потоки один раз и использовать их повторно.
Организовывать пул потоков всего для 2 задач, при том, что заранее известно, какая из них в каком потоке будет выполняться, как-то явно избыточно.
Может быть есть более простое решение? ]]> С++ для начинающих fhorse https://www.cyberforum.ru/cpp-beginners/thread3222822.html Gentoo+reactos build error - С++ для начинающих https://www.cyberforum.ru/cpp-beginners/thread3222749.html Sat, 02 May 2026 15:43:52 GMT Настройка cmake производилась командой
