CAS Performance

[Scott Battaglia]

Pete,

Does that happen all the time?  (and is this only with one user?).  The
result of an "authenticatedButNoService" call is a request to render the
viewGenericLoginSuccess page. Rendering a genericLoginSuccessView should not
result in a ticket being removed.  Tickets are only removed if you do a
renew=true with different credentials or if logout is called (unless I am
remembering wrong).

Also, CAS itself is not very memory intensive so 4 GB of memory should be
more than sufficient.  We did find in our testing (which we did on a
single-CPU machine) that the majority of the CPU time was being taken up by
Apache processes (but then we had an underpowered machine).
