Удаленный MySQL vs локальный

Тесты полная синтетика, кто скажет, что они ацтой - будет прав. На таргет машине голый вордпресс. Канал между машинами - 100 магабит череpз 3 хопа. Долбеж ведется посредством ab в такой конфигурации: ab -c 10 -n 1000 http://test1.ru:80/

Результаты тестов следующие:

Локальный мускул: Requests per second: 55.36 [#/sec] (mean)
Удаленный (без тюнинга - стандартный CentOS MySQL): Requests per second: 44.23 [#/sec] (mean)
Удаленный (с тюнингом): Requests per second: 46.40 [#/sec] (mean)



Локальный:

    ОтветитьУдалить
  2. Непонятно, объясните плз из-за чего удаленный работает быстрее?

    ОтветитьУдалить
  3. Не почему=) Он работает медленнее. Локальный - 55 запросов / секунду, удаленный - 46 за счет сетевого оверхеда.
