    -------- 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
        Temporary table size is already large - reduce result set size
        Reduce your SELECT DISTINCT queries without LIMIT clauses
    Variables to adjust:
        join_buffer_size (> 4.0M, or always use indexes with joins)

    Hello :)

    It's a good idea to let MySQL run for at least 24 hours before running a tuner to ensure more accurate results.

    Thank you.
