Thats a great resource thanks Barry. There might be some initial slowness
because it's a fairly large single page app so a bunch of scripts need to
load before it starts building ui.
Anyhow, to further the investigation I've written a script that downloads a
static image from my site over and over every 10s.
window.setInterval(function() {
var timeStart = Date.now();
var img = new Image();
img.onload = function() {
var timeEnd = Date.now();
console.log("Duration", (timeEnd-timeStart)/1000);
var output = document.getElementById("output");
output.innerHTML += "Duration " + (timeEnd-timeStart)/1000 + "<br>";
};
// note: adding a variable to the url forces the cache not to be used.
img.src = "https://blight.ironhelmet.com/images/blight_menu_bg.jpg?"; +
timeStart ;
}, 10*1000);

I have asked some of my users to run it as well to see if they see similar
number to me.
What I found was the 380k image can take between 2 and 10 seconds to
download.
It seems to be a lot more random that I would expect!
If I look at my logs on the app engine console it reports that every
request was served in under 1ms so I don't there there is a problem there.
