mysqltuner seems to be no longer maintained while you should not take any recommendation blindly it was really usefull over the years, with MariaDB some values are looking wrong Up for: 3d 17h 7m 44s (15M q [47.927 qps], 477K conn, TX: 33B, RX: 3B) [OK] Query cache efficiency: 48.1% (10M cached / 21M selects) 21M selects out of 15M queries as example :-) it would be pretty cool have a compareable tool (maybe native code) in the MariaDB setup - sadly Bash/PHP are my skills :-( ______________________________________
