It was covered some here:
and some graphs here: http://www.mattfischer.com/blog/?p=672

tl;dr is that having revoked tokens affects keystone token validation and
tokens are validated on almost every API call unless you're using some

It's not a reason to skip this idea, but its something I'm wary of since I
get the call whenever Keystone gets slow. Depending on how many revocations
it generates, I might turn it off. To be honest I'm not sure how much this
feature is used by our customers.
