PUBLIC MARKS from greut with tag performance

Although we are not comparing apples to apples, Gentoo did out-perform Ubuntu in almost every test, and sometimes by a fair margin. It does appear that optimizing for a specific CPU can yield a decent performance increase.

Of course, Gentoo offers benefits in other areas with their USE flags and being able to build a highly customized system. The question is whether the amount of time it takes is worth the benefit, and that’s a personal choice.

A quick survey shows that seven of the Alexa U.S. top ten web sites have a SCRIPT tag above their stylesheets or STYLE blocks: AOL, Facebook, Google, Bing, MSN, MySpace, and Yahoo!. These web sites don’t currently use @font-face, but if they did, they would experience the IE blocked rendering problem. This raises the concern that other web sites that are early adopters of @font-face have a SCRIPT tag above @font-face and their IE users run the risk of experiencing blocked rendering.

By using this library you can focus on implementing protocol and logic, instead of spending countless hours of writing and debugging asynchronous, non blocking, high performance socket routines.

PHP is getting massive ?

SmartSprites is a tool that will let you easily introduce and maintain CSS sprites in your designs. SmartSprites parses special directives you can insert into your original CSS to mark individual images to be turned into sprites. It then builds sprite images from the collected images and automatically inserts the required CSS properties to your style sheet, so that the sprites are used instead of the individual images.

sprites for the lazy

In the course of my diploma thesis, I evaluated the performance of several RDF stores when small pieces of information are requested from a large dataset (DBpedia infoboxes plus two very small sets). The benchmark queries employ varying levels of joins and constraints.

The Exceptional Performance team has identified a number of best practices for making web pages fast. The list includes 34 best practices divided into 7 categories.

Pylot is a free open source tool for testing performance and scalability of web services. It runs HTTP load tests, which are useful for capacity planning, benchmarking, analysis, and system tuning.

helps making XHR nice

CSS sprites are a way to reduce the number of HTTP requests made for image resources referenced by your site. Images are combined into one larger image at defined X and Y coorindates. Having assigned this generated image to relevant page elements the background-position CSS property can then used to shift the visible area to the required component image.
