Example: using fio to measure IOPS and latency

This example shows a minimal fio job to measure IOPS on 4k random read/write:

fio --name=randread --ioengine=libaio --direct=1 --rw=randread --bs=4k --size=1G --numjobs=4 --runtime=60 --group_reporting

fio --name=randwrite --ioengine=libaio --direct=1 --rw=randwrite --bs=4k --size=1G --numjobs=4 --runtime=60 --group_reporting

Quick interpretation:

  • High IOPS and low latency is desirable for database workloads.
  • Adjust numjobs, bs and direct to match your use case.
