Purpose
Efficiency History was designed to provide a snapshot of your network’s current 
efficiency. Running the efficiency test (over time) should provide similar values for 
similar network loads from a single Observer PC. In other words, this test is dependent 
on the network card in the Observer PC and the current load of the network. It is 
designed to give an aggregate view of efficiency. The value should be about the same 
when run in similar situations.
