McDonalds actually seems to have learned to take latency seriously. When their touch screen ordering systems were first deployed, the delay between tapping on an item or button was quite noticeable. These days the systems respond nearly instantaneously. I'm very glad there are people inside such a large organization that pay attention to that aspect of usability.

Now if only every other website on the internet would learn that latency matters...

It's fast food, what do you expect. ;)

It’s worrying, or perhaps just sad, that 766ms for an initial page load is considered especially noteworthy. Six thousand milliseconds is just awful.

Crazy fast but the the way all header text sizes change briefly flash between values every time you switch tabs would drive me nuts if I was responsible for this.

they gotta make sure you learn about those burgers as fast as possible.
