Here's some basics.  This is the statistics for one machine (so double would
be our daily, approx):

March 31, 2009
TOTAL AUTHENTICATIONS: 47354

PER HOUR (00 == midnight, for the non 24-hour inclined):
1711 00
1043 01
 639 02
 339 03
 213 04
 179 05
 288 06
 659 07
1485 08
2422 09
2860 10
3254 11
3239 12
3199 13
3042 14
3042 15
2777 16
2417 17
2446 18
2320 19
2422 20
2634 21
2529 22
2195 23

These are just authentications, not proxying, service tickets, etc.  On a
normal day (which these stats are), you could barely even tell the machine
was doing anything.  I think normal usage is < 5% CPU utilization each on
the new machines.

I can get other stats if you're interested.  Our portal is what drives most
of our traffic to CAS.
