Subject: how to understand the Q2Q in btt result?
Date: Mon, 26 Mar 2007 02:40:19 +0000 [thread overview]
Message-ID: <1174876819.6887.2.camel@localhost.localdomain> (raw)
from btt user guide
"Q2Q which measures the time between queue traces in the system.
This provides some idea as to how quickly IOs are being handed to
the block IO layer."
does this mean the time between queuing N request and N
+1 request?
thanks!
Ming
