Our load balancer has a graph showing outbound throughput over 1
gigabit /second. Zenoss, using SNMP to the load balancer agrees.

The Foundry shows:
  300 second input rate: 42588967 bits/sec, 15505 packets/sec, 4.40% utilization
  300 second output rate: 253773564 bits/sec, 23796 packets/sec,
25.60% utilization


Which is 35 megabytes total. So, about 93 megabytes /second off.
