[Orca-users] Graph Question: Average # Processes in Run Queue

[izsun]

Hello All,

First off - a big thank you to Blair for putting out such a great
tool as orca.

On to my question: 
in the graph entitled "Average # Processes in Run Queue",
the vertial axis has units of 100m and 200m.  My question
is what does the "m" represent ?   

I see sustained numbers in the range of 50-70m eventhough the system
is pretty much idle ... with occasional spikes up to 160m !!??

BiG kudos in advance,
-I
