Restricted Sites List Affects Performance?

I have alot of sites in my Restricted Sites zone - so was wondering if the number of addresses added to the Restricted Sites zone under the Security tab in IE, affects performance/speed? Cus i was thinking that IE has to check each site that you visit to verify if its on the Restricted Sites list or not. . . . .and the larger the list is the longer it might take for a site to load, cus it has a longer list to go through? Is that how it works, or am i totally wrong?

Thanks!!!!!

Unless your list is thousands of websites long, I don't think you need to worry.

I don't believe so because some sites load faster than others and it depends on the traffic that is currently on the site at the time
