A common method for demarcating storage performance problems is to compare the average latency difference between the host and storage. If the host-side read latency and the storage- side read latency are both large and the difference is small, it can be roughly determined that the problem occurs on the host. It may be due to improper configuration on the host side causing performance problems or problems with the network link.
