HI guys!
I'm trying use the --thinktime parameter to sleep between each io
request for ten seconds.
But, it seems not working... I'm doing something incorrect?
fio --name disktst ... --thinktime 10000000
In HOWTO, this param is described as 'Stall the job x microseconds'...
But fio dont stop between each request and continues issuing. This is
complete command line that i used:
fio --name IoRequestDelayTest --directory J\:\ --iodepth 1 --bs 4k
--size 1G --io_size 1G --direct 1 --thread --runtime 1h --time_based
--rw randread --thinktime 10000000
The J: is mounted on a USB flash drive (Kingston SE9 32GB)
Works fine for me:
./fio --name=think --size=1g --bs=4k --rw=randread --direct=1
[...]
read : io=130244KB, bw=30114KB/s, iops=7528, runt= 4325msec
./fio --name=think --size=1g --bs=4k --rw=randread --direct=1
--thinktime=1000
[...]
read : io=17668KB, bw=3340.6KB/s, iops=835, runt= 5289msec
I tried your 10s as well, works too.
