Всем привет! Искал в инете, но толком ничего не нашел. Настраиваю веб сервер в связке nginx(отдает статику)+apache2+mysql Тестирую нагрузку siege'ом. 400 запросов в секунду выдерживает в течении 1мин. при 450 и выше отваливается. я так понимаю это фигня,а не нагрузка на сервер, т.к. даже половина ресурсов не загружается. По железу: 64гб оперативной памяти 3 жестких по 1 тб в программном raid 5 процессор 8-ми ядерный.
по htop видно, что mysql сильно грузит процессор. вот конфиги mysql на данный момент.
