Comment #9 on issue 1114 by [email protected]: Typed arrays much slower than regular arrays
http://code.google.com/p/v8/issues/detail?id=1114
The perceived drop in performance seems to be caused by a change to jsperf.com's benchmark running framework that for some reason defeats V8's optimization behavior. Older versions of Chrome (that used to give better results) are slower now too.
TypedArrays themselves are not the reason for the regression, as can be seen when the benchmark's code is wrapped in functions: http://jsperf.com/typed-array-iteration/23
