Not sure if this is an ie issue or an sp3 issue a..but I've noticed repeatedly that initially going to a page is fast, but then clicking back to get to the original page can take many seconds. I see this, for example, with this forum. I'll browse to the post page quickly, then click on a post and quickly be taken to it. But then if I use back, it often takes many seconds for the page to load. However if I click on a shortcut to the posts page I get there very fast..seems like back is doing something weird. Any ideas?
