https://raw.github.com/major/MySQLTuner-perl/master/mysqltuner.pl [!!] InnoDB data size / buffer pool: 7.8G/5.5G Variables to adjust: innodb_buffer_pool_size (>= 7G) 2 GB innodb_buffer_pool is a joke for a dataset of 33 GB that leads in permanently I/O on mixed load at the chances are high that there are times where nothing needed to operate is in the buffer_pool and on concurrent load mysqld ends in repeatly swap data in and out of the pool at least all repeatly accessed tables should fit permanently in the buffer
