Improving UX through front-end performance

Engineer Lara Swanson writes an excellent article for A List Apart on how overall UX design can be greatly improved with some performance optimization. It’s true some of her suggestions should be obvious (e.g. sprites, cutting down on HTTP requests), but there’s still real insight here. It’s an especially important read for designers: I’ve seen way too many beautiful designs that have way too many requests and inefficiently load imagery.
