On TryStack we were able to speed up the dashboard by tuning keystone,
the token ttl should be reduced to a few hours, I think we used 3 and we
added memcached to store the tokens.

The slow down for us was looking up tokens in a database that was full
of tokens that had not expired. You may need to expire all the old
tokens to get the benefit of this.
