How do i stop/delete long running scripts in IE 11 windows 8.1

Slow page load, choppy scrolling on some websites, and frequent crashes, and long running script notifications were a huge issue for me.  Here is what I did to fix it:

1) Reset IE: Internet Option > Advanced Tab > reset button

2) Load Tracking protection lists from (here):

Name                EasyList

Name                EasyPrivacy

Name                Indonesian EasyList

Name                PrivacyChoice

Name                Stop Google Tracking

Name                TRUSTe

3) Install IE add-on DoNotTrackMe.

4) Turn off smooth scrolling: Internet Options > Advanced Tab > Browser Heading > last item called "smooth scrolling" > uncheck.

My browsing is now screaming fast, even on notoriously bad websites like tmz.com.

Hopefully that might help.
