I knew that I posted a more recent, more complete list some place before... and here it is

The site that's using it has roughly 1400 visitors on it with in a two hour period all day long. No slow downs except for when someone visits the "Who's Online" page, they get a 1 second delay. But I believe that's mostly because the page being displayed is a mile long, filled with URL links pages which everyone else is browsing.
My best advice, copy/paste the list to your site. Keep it up for a few days. If you notice that your site feels laggy (which it probably will not), replace it with one of the older, less complete lists.
