On the heaviest loaded machine:

10:10:01 AM       sum   1637.48
10:20:01 AM       sum   1640.73
10:30:01 AM       sum   1653.58
10:40:01 AM       sum   1617.78
10:50:01 AM       sum   1727.97
11:00:01 AM       sum   1767.88
11:10:01 AM       sum   1798.93
11:20:01 AM       sum   1782.14

Average:         INTR    intr/s
Average:          sum   1365.55

This is on a dual processor machine with a total of 8 cores.

The highest I see on any of the machines for the last 24 hours is a 
brief (one ten minute interval) peak of 5300 intr/second during system 
backups and nothing over 3000 otherwise.
