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.

I am really trying to get a handle on the Load(*) graph. I've only found one message in the archive and little-to-nothing in the manual.

Is there something else on this topic out there? I sure would like some detail.
