-------- Recommendations -----------------------------------------------------
General recommendations:
    Run OPTIMIZE TABLE to defragment tables for better performance
    MySQL started within last 24 hours - recommendations may be inaccurate
    Adjust your join queries to always utilize indexes
Variables to adjust:
    join_buffer_size (> 128.0K, or always use indexes with joins)
    thread_cache_size (> 8)
    innodb_buffer_pool_size (>= 21M)
