> How many logins per hour can CAS handle?

As many as your infrastructure supports ;)  Seriously, it may be
helpful to distinguish between logins and service accesses since login
is far more resource intensive generally than simply granting and
validating a ticket for service access (assuming no proxies, and even
then still probably lighter weight).

We can easily handle 10 auths/sec per node, which scales to 36000/hr
per node, on our JPA backend.  You're well below where 4 nodes should
be straining in my opinion, but that assumes the other system
components (LDAP, Oracle) can scale linearly with your Java app
servers.  That is a fairly dubious assumption in my experience.

I encourage you to do some testing yourself using one or more of the
JMeter tests attached to
https://wiki.jasig.org/display/CASUM/Apache+JMeter.  If I had to
guess, I'd imagine your database is the bottleneck, but some stress
testing will help provide some evidence.
