Народ поделитесь опытом оптимального кеширования базы? В магазине уже около 17 тысяч единиц товара и используется встроенный фильтр по цене который грузит базу на раз!
изучал кеширование и в результате собрал вот такой файл конфигурации для одноядерного сервера с 6 Гигами оперативки.
Посмотрите где какие правки если что внести или вполне подходящий?
В итоге как я понимаю отдалось 1024 Мегов под кеш базы вместо базовых 64Мега
+ я еще подтянул Мемкешед и выставил ему вместо базовых 64 Мега - 512 Мегов
Но субъективно по моему не сильно улучшилась скорость - утром летал а сейчас когда на сайте 50-т человек то по моему так же как вчера до увеличения кешей у мемкеш и базы
