You should use PerfTestRunner.now. It uses performance.webkitNow or Date.now, whichever is available.

> PerformanceTests/SVG/SvgNestedUse.html:62
> +            while (times.length > 10) { times.shift(); }

Nit: No curly brackets around a single statement. Also, times.shift() should be on the next line by itself indented by 4 spaces to the right of while.

You don't want to just report fps instead?

Please don't use one letter variable names.

No curly brackets around a single statement.

'fps' holds the average time for the last 10 frames at this point. Updated the name to reflect that.
