Notes:

* A microsecond is 1/1000000 of a second.

Response time indicates the time taken from when the storage system starts processing an I/O request until it returns a completion notification. On the other hand, the response time that can be checked on the host side generally refers to the turnaround time from when the host issues an I/O request until it receives a completion notification. Therefore, when comparing the response time shown in this performance information with the response time measured on the host side, there may be some discrepancies.
