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.
