So I was looking at archive.macfixitforums.com and I found that the page loads were being held up by a couple of links to an ad server called madstage.com.com that wasn't responding. If you block that domain with an ad blocker or add the following to your /private/etc/hosts file, it loads quickly again.
127.0.0.1 madstage.com.com
Then in the Terminal, clear your DNS cache with:
dscacheutil -flushcache
