@Wayne-Workman Yes i’ll be changing the client check in time after posting the required information from MySQLtuner for @george1421.
Yes 4 Cores would be nice, however due to fog not a being a critical server on our production environment it’s best not to take away resources from other servers. This might change in future though
@george1421 Let me know if this is good info for you, I’m looking to update fog in the next couple of weeks. Maybe to the latest development version

-------- Recommendations ---------------------------------------------------------------------------
General recommendations:
Restrict Host for 'fogstorage'@% to fogstorage@SpecificDNSorIp
UPDATE mysql.user SET host ='SpecificDNSorIp' WHERE user='fogstorage' AND host ='%'; FLUSH PRIVILEGES;
Configure your accounts with ip or subnets only, then update your configuration with skip-name-resolve=1
When making adjustments, make tmp_table_size/max_heap_table_size equal
Reduce your SELECT DISTINCT queries which have no LIMIT clause
Before changing innodb_log_file_size and/or innodb_log_files_in_group read this: https://bit.ly/2TcGgtU
Variables to adjust:
query_cache_size (=0)
query_cache_type (=0)
query_cache_limit (> 1M, or use smaller result sets)
tmp_table_size (> 16M)
max_heap_table_size (> 16M)
innodb_log_file_size should be (=16M) if possible, so InnoDB total log files size equals to 25% of buffer pool size.
