#10895 closed enhancement (fixed)

The doScrollCheck ie hack in bindReady degrades ie7 performance for no reason whatsoever

Description

The doScrollCheck hack using in bindReady is only necessary in ie6 and yet it runs in every ie browser costing 80% of the time it takes jquery to initialize itself.

It has been reported before and dismissed, why do you insist on having this unnecessary overhead in the code?

I cant show this using jsperf, but it is trivial to see if you profile jquery in ie7 or 8 using dynatrace ajax edition. Lets get rid of this annoying pageload overhead.
