Всем доброго дня!
Имеется 3 контейнера:
nginx (192.168.0.1; 1 GB)
apache (192.168.0.2; 1 GB) PHP + APC, memcached (сессии)
mysql (192.168.0.3; 4 GB)
MySQL ~15-20к запросов/сек на запись/чтение/изменение
При легком тестировании нагрузки слишком высокое время отклика, порядка 0.4-0.7 сек
Подскажите, пожалуйста, в какую сторону смотреть? Спасибо!
