Hello i have a new dedicated server and would like to optimize the my.cnf file. Can anyone recommend what to change in the below MySQLTuner output


Code:

-------- Recommendations -----------------------------------------------------
General recommendations:
    Run OPTIMIZE TABLE to defragment tables for better performance
    Enable the slow query log to troubleshoot bad queries
    Set thread_cache_size to 4 as a starting value
    Increase table_cache gradually to avoid file descriptor limits
    Read this before increasing table_cache over 64: http://bit.ly/1mi7c4C
Variables to adjust:
    query_cache_size (>= 8M)
    thread_cache_size (start at 4)
    table_cache (> 400)

Hello :)

You might receive user-feedback on specific values to utilize, however if not, you could try adjusting the values based on the output under "Variables to adjust" from the tuning script.

Thank you.
