Amazon and others found that removing 100 milliseconds of latency improves sales by 1%.
But latency on the web is hard to overcome.
Cheating latency
instant.page uses just-in-time preloading — it preloads a page right before a user clicks on it.
On desktop
Before a user clicks on a link, they hover their mouse over that link. When a user has hovered for 65 ms there is one chance out of two that they will click on that link, so instant.page starts preloading at this moment, leaving on average over 300 ms for the page to preload.
Another option is to preload when the user starts pressing their mouse, right before releasing it. This makes for virtually zero unused requests while still improving page loads by 80 ms on average.
On mobile
A user starts touching their display before releasing it, leaving on average 90 ms for the page to preload.
Another option is to preload links as soon as they’re visible.
