An Event Apart: Performance as User Experience
by Luke Wroblewski April 3, 2018
In his Performance as User Experience presentation at An Event Apart in Seattle, Aaron Gustafson shared a number of ways to optimize Web page performance. Here's my notes from his talk:
- Our jobs as designers is to reduce friction for our users. Poor performance causes friction and can negatively impact key metrics like conversion and revenue.
- How do Web pages load: when you enter an address in a URL bar, a DNS look-up replies with an IP address, then there's a TCP handshake followed by the actual request for files/data, once there's a response the browser can actually do something.
