| F.A.Q. • SupportLinux tool - FIO (Bandwidth tests)
1) Random write IOPS (4 KB for single I/O):
fio -direct=1 -iodepth=32 -rw=randwrite -ioengine=libaio -bs=4k -numjobs=4 -time_based=1 -runtime=60 -group_reporting -filename=/dev/vdx -name=test
2) Random read IOPS (4 KB for single I/O):
fio -direct=1 -iodepth=32 -rw=randread -ioengine=libaio -bs=4k -numjobs=4 -time_based=1 -runtime=60 -group_reporting -filename=/dev/vdx -name=test
3) Sequential write throughput (write bandwidth) (128 KB for single I/O):
