fio is a versatile tool for measuring I/O performance, and it can produce a lot of output, which can sometimes be difficult to interpret. When fio reports IOPS (Input/Output Operations Per Second), it often provides separate results for read and write operations, as well as an aggregate total. The output from fio might look something like this: read: IOPS=10k, BW=40MiB/s (42MB/s)(1000MiB/25003msec) write: IOPS=15k, BW=60MiB/s (63MB/s)(1500MiB/25003msec) In this example: The read: IOPS=10k means that the system was able to perform 10,000 read operations per second....
