Status: New Owner: ---- New issue 1663 by joaebert: Float64Array Performance http://code.google.com/p/v8/issues/detail?id=1663
The performance of Float64Array is not as good as expected in comparison to an Object or untyped Array. Also it is much worse than storing a pair in an Array.
Please see http://jsperf.com/array-vs-linkedlist for a benchmark and full source code.
Since Float64Array is advertised as a "typed array" I would expect its performance to be significantly better than using two Array objects that store a double.
