Vitaly Friedman swings wide with a massive list of performance considerations. It’s a well-considered mix of old tactics (cutting the mustard, progressive enhancement, etc.) and newer considerations (tree shaking, prefetching, etc.). I like the inclusion of a quick wins section since so much can be done for little effort; it’s important to do those things before getting buried in more difficult performance tasks.
Speaking of considering performance, Philip Walton recently dug into what interactive actually means, in a world where we throw around acronyms like TTI:
But what exactly does the term “interactivity” mean?
I think most people reading this article probably know what the word “interactivity” means in general. The problem is, in recent years the word has been given a technical meaning (e.g. in the metric “Time to Interactive” or TTI), and unfortunately the specifics of that meaning are rarely explained.
