html() uses a regular expression that performs badly in IE > 9 #2563
Description
rnoInnerhtml = /<(?:script|style|link)/i
The above causes significant performance issues in IE 10 IE 11 and EDGE when inserting large amounts of HTML using the html function.
It can be re-written as the following:
rnoInnerhtml = /<script|<style|<link/i,
The above performs at the same level in other browsers and exponentially faster in IE .
My tests show for two columns for 4096 rows the difference is 18 seconds versus 5 milliseconds (IE 11).

Note when testing you the first test will always be slower than the second in chrome / firefox
Ticket logged at Microsoft however i think jQuery should be fixed anyways.
