Помню на прошлом форума тема была очень популярная, сегодня тоже столкнулся с этим) в принципе взял гугл в руки кое что нашёл для себя, но мне показалось визуально что innodb стало еще больше тормозить чем по дефолту где её выделялось всего 20 мб про все.

Конфиг - Core 2 quad, 6GB, для меня важно что бы mysql не хавал гигабайт от памяти, ведь кроме него есть еще и сервер)
где можно поправить ?(уменьшить, увеличить значение) для более высокой производительности.
