-------- 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
    When making adjustments, make tmp_table_size/max_heap_table_size equal
    Reduce your SELECT DISTINCT queries without LIMIT clauses
    Increase table_cache gradually to avoid file descriptor limits
Variables to adjust:
  *** MySQL's maximum memory usage is dangerously high ***
  *** Add RAM before increasing MySQL buffer variables ***
    query_cache_size (> 32M)
    join_buffer_size (> 8.0M, or always use indexes with joins)
    tmp_table_size (> 256M)
    max_heap_table_size (> 128M)
    table_cache (> 300)

Whats so sad? It's Sunday, everyone is offline enjoying the weekend and you've only posted a little over 9 hours ago, late on a Saturday night.

If you're in a rush, have a closer look at other similar threads asking the same question for tips on how you can tweak your system on your own.

Here's a tip to get you going in the right direction, you should make sure MySQL has been up for at least 24 hours before assuming MySQLTuner is giving you accurate details.

From your post above, a snip that says yours has been up 48 minutes at time of paste:

-------- Performance Metrics -------------------------------------------------
[--] Up for: 48m 53s (768K q [262.065 qps], 5K conn, TX: 412M, RX: 158M)

Optimizing your server is not necessarily a cPanel thing, it's about your server and its hardware. Those kinds of details and tips can be found in a much larger scale outside these forums via your favorite search engine.

cPanelTristan and others who assist in explaining the output of MySQLTuner and ways to tweak your system on this forum, do it to be helpful.

It's not a requirement on these forums that anyone answers your posts, even more so on a weekend.
