I am using fio to test how much iops my server can offer. My conf file says to write a 20GB file and read it. THe results show iops=27291. But the test last only 10 seconds. I wonder if the test last 2 hours for example, I would have a more accurate result about my server IOPs.
# cat fio/fio-readwrite-20g.fio [global] ioengine=posixaio rw=readwrite size=20g directory=/home/ustore/fio thread=10 write_bw_log=fio-test write_iops_log=fio-test write_lat_log=fio-test [fio-readwrite-20g]
