There's plenty of experimental data proving that the slower your website loads and displays, the less people will use it. [Google found that] the page with 10 results took 0.4 seconds to generate.

  CSS box-shadow Can Slow Down Scrolling

Working on one of the Chromebooks Google lets you borrow on Virgin America flights, I noticed scrolling down the page on my airbnb.com dashboard was much slower than on my normal laptop. I chalked it up to weak Chromebook hardware, but other sites were scrolling just fine. box-shadow had caused slow scrolling on our search results page before, so I did some investigation.I used Chrome's Timeline tab to see the duration of paint events on the page.

  Circumventing browser connection limits for fun and profit

A few days ago, this video hosted by metacafe popped up on digg, explaining how to increase site download times by tweaking your browser settings to increase connection parallelism. To explain why this works, let’s step back a bit to discuss how browsers manage server connections. In building any application, developers are often required to make ‘utilitarian’ choices. Pretentiously paraphrasing Jeremy Bentham, ‘utilitarian’ describes an approach that â...
