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.
