    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
    Adjust your join queries to always utilize indexes
    Set thread_cache_size to 4 as a starting value
    Variables to adjust:
    join_buffer_size (> 128.0K, or always use indexes with joins)
    thread_cache_size (start at 4)
    open_files_limit (> 10510)
    innodb_buffer_pool_size (>= 12M)
