This is interesting if you wish to compare your load rate with the rate of your competitors. According to recent research, 250 milliseconds is what keeps your customers from choosing your competitor over you. And each 250 milliseconds delay may mean a significant loss in your revenue. For Amazon, 100 milliseconds increase in speed rate meant 1% increase in the sales money. This equals $1.6 billion in revenue (for Amazon) per just one second.
