-------- Recommendations -----------------------------------------------------
General recommendations:
    Run OPTIMIZE TABLE to defragment tables for better performance
    MySQL started within last 24 hours - recommendations may be inaccurate
    Enable the slow query log to troubleshoot bad queries
    Optimize queries and/or use InnoDB to reduce lock wait
Variables to adjust:
    query_cache_limit (> 16M, or use smaller result sets)
