Notes

"I need to be clear here: If you have Firebug installed you are probably not getting fast Javascript. Firebug doesn’t have to be active on your current page. If you have the grey icon on your status bar, you have probably disabled the JIT."

Doloto

webdev javascript .net performance optimization imported:pinboard

Notes

Sounds interesting. Too bad it's in .NET. "Doloto is an AJAX application optimization tool, especially useful for large and complex Web 2.0 applications that contain a lot of code, such as Bing Maps, Hotmail, etc. Doloto analyzes AJAX application workloads and automatically performs code splitting of existing large Web 2.0 applications. After being processed by Doloto, an application will initially transfer only the portion of code necessary for application initialization. The rest of the application’s code is replaced by short stubs—their actual function code is transferred lazily in the background or, at the latest, on-demand on first execution. Since code download is interleaved with application execution, users can start interacting with the Web application much sooner, without waiting for the code that implements extra, unused features."

To Sprite Or Not To Sprite at Vladimir Vukićević

webdev css sprites browsers optimization imported:pinboard

Notes

"The biggest problem with CSS sprites is memory usage. Unless the sprite image is carefully constructed, you end up with incredible amounts of wasted space. My favourite example is from WHIT TV's web site, where this image is used as a sprite. Note that this is a 1299x15,000 PNG. It compresses quite well — the actual download size is around 26K — but browsers don't render compressed image data. When this image is downloaded and decompressed, it will use almost 75MB in memory (1299 * 15000 * 4)."
