I've often wondered about the odd pauses IE will sometimes have when browsing. There are times I've had to go so far as to start up a new instance. So I was interested when I stumbled across this post from last December. The author is talking about 5 year old behavior, but I still see those symptoms. I've seen others comment on IE oddness as well - have a look here, for instance. So what gives? Is IE specifically optimized for IIS, or is there something else going on here?
