Everything was running nice and fast as of sometime last week for both of our primary servers and after checking some simple bundle downloads (both file copies and individual MSI bundles) we found that the throughput on the server is about 1Mb (we have a 1Gb nic on the server). Running another test copying a file down from a shared folder on the server was insanely fast so the network is running fine.

Secondly, after running some packet sniffing, it appears that all the content traffic is going over port 80 now, where before, it seemed to be running over 443.

I checked the firewall and it is off per our standard.

No threads talking about slowness seem to work for us.
