 When logged in to administer anything at the network level it takes 19
 seconds for a response. When I log in to a subdomain under the network
 response time is excellent. What is broken at the network level? Any
 thoughts on how to debug or figure out this issue would be so much
 appreciated. I have removed all plugins that I do not use. I can also say
 that when I initiated the update to the core it was instantly noticeable
 that the response time was slower...crazy slow. I hope someone knows what
 this might be. I even updated to the most recent version of Wordpress
 ..4.5.1 and it didn't fix the issue.
