-------- Recommendations -----------------------------------------------------
General recommendations:
    Run OPTIMIZE TABLE to defragment tables for better performance
    Enable the slow query log to troubleshoot bad queries
    Reduce or eliminate persistent connections to reduce connection usage
    Increase table_cache gradually to avoid file descriptor limits
    Optimize queries and/or use InnoDB to reduce lock wait
Variables to adjust:
    max_connections (> 151)
    wait_timeout (< 28800)
    interactive_timeout (< 28800)
    table_cache (> 400)

# Run program with --help to get a list of available options and with
