JTS 2017 знаю, что старый, но возможно кому и пригодится
Кстати у меня такая же проблема как у sergebaz, если убрали с репозитория как быть?По смотрите в зависимости проекта мавен, наверное либу с репо убрали и он ее не видит

General recommendations:
Run OPTIMIZE TABLE to defragment tables for better performance
Set up a Secure Password for user@host ( SET PASSWORD FOR 'user'@'SpecificDNSorIp' = PASSWORD('secure_password'); )
MySQL started within last 24 hours - recommendations may be inaccurate
Reduce or eliminate unclosed connections and network issues
Variables to adjust:
thread_cache_size (> 24)
innodb_buffer_pool_size (>= 200M) if possible.Скрипта с этих сурсов?mysqltuner можно попробовать запустить, возможно он сможет выявить проблему если она действительно в mysql, но это не точно.
Пример теста этого "скрипта"

Это отдельный perl-скрипт для оптимизации настроек самого mysql. Оптимизация настроек подключения индивидуальна, в зависимости от используемых типов хранения данных, размеров данных баз и конечно характеристики железа сервера (к-во озу, к-во ядер и т.п.).Скрипта с этих сурсов?
