Improving HTML5 Canvas Performance. Introduction HTML5 canvas, which started as an experiment from Apple, is the most widely supported standard for 2D immediate mode graphics on the web.
Many developers now rely on it for a wide variety of multimedia projects, visualizations, and games. However, as the applications we build increase in complexity, developers inadvertently hit the performance wall. There’s a lot of disconnected wisdom about optimizing canvas performance. This article aims to consolidate some of this body into a more readily digestible resource for developers. Note that this article does not go into usage of HTML5 canvas. Performance testing To address the quickly changing world of HTML5 canvas, JSPerf (jsperf.com) tests verify that every proposed optimization still works.

For the purposes of conformance for user agents designated as supporting the suggested default rendering, the term "expected" in this section has the same conformance implications as the RFC2119-defined term "must". 10.1 Introduction In general, user agents are expected to support CSS, and many of the suggestions in this section are expressed in CSS terms.
