Форум пользователей MySQL

Столкнулся с проблемой, есть скрипт который перебирает бинарное дерево (начиная с самой вершины), ища где есть свободная ветка (то есть под какой ячейкой незанятое одно из двух мест). Когда в дереве становится около 1000 элементов, скрипт работает довольно медленно (0.5 - 1 сек), а таких запросов происходит много, и в результате скрипт выполняется очень долго, при этом процессор и ОЗУ почти не нагружается (о чем говорит htop). Как выделить mysql больше ресурсов?
Пытался настроить по этой статьи ( https://ruhighload.com/index.php/2009/0 … %80%D0%B0/ ), но у меня нет большинства параметров о которых там написано, в конфигурационном файле, а если их пишу самостоятельно, то ничего не меняется.
Помогите пожалуйста.

/etc/mysql/my.cnf

#
# The MySQL DATABASE server configuration file.
#
# You can copy this TO one OF:
# - "/etc/mysql/my.cnf" TO SET global options,
# - "~/.my.cnf" TO SET user-specific options.
#
# One can USE ALL long options that the program supports.
# Run program WITH --help to get a list of available options and with
# --print-defaults to see which it would actually understand and use.
#
# FOR explanations see
# http://dev.mysql.com/doc/mysql/en/serve … ABLES.html

# This will be passed TO ALL mysql clients
# It has been reported that passwords should be ENCLOSED WITH ticks/quotes
# escpecially IF they contain "#" chars...
# Remember TO edit /etc/mysql/debian.cnf WHEN changing the socket location.
