Subject: Clat calculation
Date: Mon, 18 Sep 2023 10:54:37 -0600	[thread overview]
Message-ID: <CAJ3QLKcSM6oRGuyzJ4tquzP5UUfju7KQfkuBZpHdz_eGHL0Gvw@mail.gmail.com> (raw)

Hello,
I am seeing a stiff delta between the fio clat vs blktrace data and
wondering how fio clat is measured in terms of the I/O processing
step. In blktrace, I measured the time delta between the complete(C
action) and issued(D action) per LBA basis.

Can you tell me how fio clat is calculated please?

Thank you,
Jay.
