Things will be slower in large part because of limitations in the 
keystone api -- in some cases where we were able to do one big ldap 
query to answer a question like "what projects am I in?" we now have to 
do clumsy things like ask each individual project "am I a member of 
you?" which adds up to a lot of REST calls.

Most everything is cached, though, so the slow page loads should only 
happen occasionally.  If you run into a case where performance is 
unbearably slow, let me know and I'll see about optimizing.
