JS Object Storage Performance
Precreate 50.000 objects (globally stored). After this create 10.000 new (non stored) objects inside a loop.
Keep global storage over runtime.
The performance in IE is poor (~1150ms for each loop), compared to the same stuff executed without so much precreated objects (previous example).
It makes no difference if we use a global or a local variable here. It's identical to LocalObject_2.html.
