Fastest way to sort 32bit signed integer arrays in JavaScript?

I’ve tested typed arrays, the QSIP version seems to be good in modern browsers:

2 000 000 elements

          QSIP_TYPED | RDXIP_TYPED |  QSIP_STD | RDXIP_STD
----------------------------------------------------------
Chrome  |    300          1000          600        1300
Firefox |    550          1500          800        1600

 IE 10+   |   FF 4+  |  Chrome 7+  |  Safari 5.1+  |  Opera 11.6+
