Optimizing Page Load Time

Submitted by matt 27 days ago (more from die.net)

While working on optimizing page load times for a high-profile AJAX application, I had a chance to investigate how much I could reduce latency due to external objects. Specifically, I looked into how the HTTP client implementation in common browsers and characteristics of common Internet connections affect page load time for pages with many small objects.

Nice overview of what's essentially Firebug for IE. Wondering what the difference between Document Mode and Browser mode is? Document Mode allows you to manually choose which rendering engine you want IE to render the page with. Browser Mode changes both the Document Mode, and the User Agent string, which allows Internet Explorer 8 to lie about who it says it is.

diffable

Submitted by matt 62 days ago (more from code.google.com)

A method for reducing page load latency by transmitting differential encodings of static files. It works by sending deltas between versions of files that reside in a browser's cache. Files such as Javascript, HTML, and CSS are often updated every week or more, but change very little between versions. This method significantly reduces the bandwidth and transmission time for these files.

Data URIs make CSS sprites obsolete

Submitted by matt 65 days ago (more from nczonline.net)

The problem is that HTTP requests are a major performance bottleneck for web pages. The more requests you have, the longer it takes your page to load and the slower it is. In short, data URIs allow you to embed images (and other files) directly into HTML and CSS. Since all of the data is represented locally, there is no extra HTTP request required to access the information.
