    -------- Recommendations -----------------------------------------------------
    General recommendations:
        Run OPTIMIZE TABLE to defragment tables for better performance
        Increasing the query_cache size over 128M may reduce performance
    Variables to adjust:
        query_cache_size (> 969M) [see warning above]
        innodb_buffer_pool_size (>= 2G) if possible.
        innodb_buffer_pool_instances (=1)
    My Software:
    • Litespeed 5.0.5
    • PHP 5.6
    • MySQL 5.6.23

    Hello :)

    Yes, I suggest reviewing the URL referenced in the previous post in order to troubleshoot the load issues on your system.

    Thank you.
