With regards to how responsive the SmartRemote / myServer is - it is near instant. No issues. All perceived delays are due to the hardware that you are attempting to control. For example, I hit the POWER button to turn on my Samsung TV and ONN box. The TV reacts quickly. The ONN takes like 15 seconds to wake up. But that's on the ONN box, not SmartRemote or myServer or network. Turn OFF is immediate.
Navigating the online menus of Hulu / Netflix / etc are near immediate.
