"You

NFS."
[Chuck] How can I tell which ones are response times? This name doesn't give an indication. The same goes for many other time variables.
"It
will then calculate and plot how the queue-depth changes throughout the
capture."
[Chuck] How can I get
the details on how this works? Source code? If so, how do I get this
part?
I am
really wanting to understand how this works so I can apply this to analysis that
I do. That's why I'm asking for more detail.
Thanks
for your patience, I look forward to hearing from you again.

LOAD is used to view/analyze the queue-depth for command-response
style protocols.
You use on "response time" fields, like
rpc.time for NFS.
It will then calculate and plot how the
queue-depth changes throughout the capture.
For ease of implementation it
uses integer math for these calculations, as such a value of 1000 on the Y-axis
represents 1(ONE) I/O in flight.
This is very useful since it is shows
the relation in performance between the initiator and the target and is the only
real way of measuring initiator(client)
performance.
