@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
Server has been up for ~8 Days
