SunSpider can be a javascript based mostly optimization suite which aims to detail weaknesses in the browser or plugin's javascript rendering.
Basically, it tells you how fast a browser will run core javascript functions once your plugin is installed. Or in the situation of browser vendors it tells them how very well they did on their new javascript rendering engine. It is possible to attempt the take a look at by yourself here.
Even though SunSpider is open base and component with the Webkit mission, that hardly implies that this report complete of resource code analysis from YCombinator thing is exact.
From the post posted by "Seldo", founder of Awe.sm, suggests which the IE9 team purposely cheated inside IE javascript rendering motor updates to the sole purpose of finding high marks around the Sunspider take a look at, and not to increase basic javascript overall performance. He comes to this conclusion mainly because it's the sole logical conclusion he could occur up with for IE optimizing within a site the place webkit didn't.
