For those coming to this thread in the future, Internet speed and AC speed are two separate issues. The only time Internet speed has DIRECT bearing on AC performance is when AC is calling externally - e.g. eRX (as soon as the window starts to open), and calls to Updox for portal interactions.
There is the 'beloved' phone home that AC does when starting, but I haven't instrumented AC in a while to see when else it calls out.
Note Bitte - this is a VERY different discussion if you run ACPM.
