Правильная настройка mysql
Добрый вечер Уважаемому сообществу, начинаю осваивать администрирование виртуального сервера. У меня на нем два форума phpbb 3.2 и два сайта на Вордпресс
3 X Intel(R) Xeon(R) Gold 6138 CPU @ 2.00GHz, 3019 MiB оперативки
Начал с разгона mysql
Вот такие у меня сейчас в my.cnf, может будут советы как еще оптимизировать? Спасибо

# 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/server-system-variables.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.
