Installing a client would remove a lot of lag because those who DO NOT want to create a new user and would rather search around the site as a guest would be forced to download the client first in order to do so. And the "common" user wiil not want to download something just to look at a site, it would seriously cut down on all the guest users abilities to lag up the system. A user who is pissed at the site and its users can load the front page and then just hold down the shift key and click EVERYTHING that has a link to it. This would bog down his connection and ours yes, unless he had a good one. It's funny how hate takes much more energy to put forth than love does.
