I agree. Very frequently it times out in getting new messages, or just takes forever. I pressed the 'new messages' button some 15 min's ago, and nothing happened for 30 seconds, so I went to another web page. Don't know how long it took to come up, but it sure was slow enough for me to give up.
This is consistent with both home and work, and has been happening as long as I've been on the forum.
