New issue 2190 by [email protected]: Performance on TypedArray creation
low
http://code.google.com/p/v8/issues/detail?id=2190
Reading and writing to and from existing TypedArrays very fast:

- http://jsperf.com/typedarray-write/3
But in contrast creating a new TypedArray is very slow:
- http://jsperf.com/typedarray-create
This is a killer for scenarios when you are using temporary objects inside
the functions (Native) in contrast of using an external singleton as
temporary object (TempObj):
- http://jsperf.com/typedarray-lookat/3
if you are using temporary Arrays inside the function (Mixture / Mixture
TempObj) it doesn't result in a huge performance decrease.
