Yup created a ticket already. CPU and memory usage looks fine. Should definitely be server related...If it's a managed server, I would have your host check first. Maybe look at current CPU usage, etc ... anything to see why it's running slow. Since you say it's multiple sites affected, it's probably server related.
could be web host server issues as re-running pingdom test for your site has 1.7s now not 20s, still doesn't help if you have 464KB sized header banner !http://tools.pingdom.com/fpt/#!/duYW0s/iheartbulldogs.club
Someone please tell me what I can do improve this...
