Internet Explorer Canvas Tag Massively Faster Than Chrome

In other words, the code at http://www.nerds-central.com/Linear-Scan-Test.html looks like this code is using the antiquated setTimeout() method of determining frame rate.

A better way to do it, at least for chrome and firefox users, is to use the newer requestAnimationFrame() function: http://paulirish.com/2011/requestanimationframe-for-smart-an... This allows for the browser to notify the script when its ready to display a new frame, resulting in more efficient animation execution.

Using FPS for benchmarking is good, but suffers from the same shortcomings as glxgears.

Usually when developing web apps I get things working in Firefox first then test in the other browsers.

Lately I've been doing some work with Canvas and found IE to be the fastest for drawing large (many points) polygons(* ). I never thought I'd say this but it's been a lot more pleasant to develop in IE, at least during the proof-of-concept stage where I haven't done much optimizing or caching.

(* ) I haven't benchmarked whether it's the canvas drawing or javascript engine (or both) that's faster, just that overall I'm getting 30+% better performance from IE
