The mythical “fast” web page
Web performance can mean a lot of different things to a lot of different people. Fundamentally, it’s a question of how fast a web page is. But fast to whom?
When this page loaded moments ago, was it fast? If so, congratulations, you had a fast experience. So ask yourself, does that make this a fast page? Not so fast! Just because you had a fast experience doesn’t mean everyone else does too. You might even revisit this page and have yourself a slow experience.
