My appleTV(s) are on their own dedicated 5GHz network. I did this because I did not want any 2.4GHz devices connecting and slowing them down. But I have found that even on their own network, the time from when I click play to the time they start playing seems to vary quite a bit. I have tried to optimize my network by using wide channels, and using only the 5GHz band. I even put on a password to make sure no neighbors are loitering. I do realize that the actual time depends on the size of the movie file, among other factors. But I wanted to get an idea of what other people are experiencing. Most of the lag I am seeing seems to be before the blue progress bar appears. Once the blue bar appears, it begins playing almost immediately. Sometimes I select the movie from the menu and wait 1-2 minutes for the blue progress bar to appear. Other times it only takes a 10-20 seconds. So what is your experience? To be helpful, please state your network type(5GHz, 2.4GHz, shared), and general observations.
