-------- Recommendations -----------------------------------------------------
General recommendations:
Run OPTIMIZE TABLE to defragment tables for better performance
MySQL started within last 24 hours - recommendations may be inaccurate
Variables to adjust:
query_cache_type (=1)
innodb_buffer_pool_instances (=1)
