apache тест производительности сервера бенчмарка необоснованный результат

0 голосов
/ 08 апреля 2020

Я проверяю общую производительность моего домашнего сервера с помощью теста apache. Тем не менее, когда я тестирую сервер с 1 пользователем и 10000 запросов, количество запросов в секунду постоянно составляет около 250 (в среднем), но когда я провожу тест с 10 пользователями и 10000 запросами, оно сообщает, что количество запросов в секунду составляет около 1134. Я протестировал эти два сценария ios несколько раз и получил этот необоснованный результат. Я думаю о том, почему он прыгает примерно с 200 req / se c до 1134 req / se c. Не должен ли первый тест также дать тот же или близкий результат? Оба теста отправляют более 1000 запросов.
