What are the most important changes browsers could make to improve performance? This document is my answer to that question. This is mainly for browser developers, although web developers will want to track the adoption of these improvements.

LABjs (Loading And Blocking JavaScript) is an open-source (MIT license) project. on-demand JavaScript loader, capable of loading any JavaScript resource, from any location, into any page, at any time. LABjs by default will load (and execute) all scripts in parallel as fast as the browser will allow. However, you can easily specify which scripts have execution order dependencies and LABjs will ensure proper execution order. This makes LABjs safe to use for virtually any JavaScript resource, whether you control/host it or not, and whether it is standalone or part of a larger dependency tree of resources. It uses an expressive, chaining API to specify which scripts to load, and when to wait ("block"), if necessary, for execution before proceeding with further execution.

ealing with browser caching is a balancing act. On one hand, you aim to minimize load times and bandwidth use by ensuring that images, scripts, and style sheets are cached by your visitors; however, you still want to ensure that they’re accessing the most recent versions of all your files. In this article, I’ll show you a few methods for controlling how your site’s files are cached by browsers so you can achieve the best of both worlds: maintaining optimal performance while ensuring that any updates are seen immediately, without a hitch by all of your users.

The following tables compare support of HTML 5 differences from HTML 4 for a number of layout engines. The specification is still a working draft, not a recommendation, and thus not stable.
