-------- 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
    Increase table_cache gradually to avoid file descriptor limits
Variables to adjust:
    join_buffer_size (> 128.0K, or always use indexes with joins)
    table_cache (> 400)

Yes, i have cleared cache of the browser. On every machine, warnings are shown. But periodically... They are not always present. My traffic made significant fall.

What to do next?
