how to fully load RAM while stressing SSD using fio

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hello,

I would like to stress my SSD and RAM with fio and I use command

fio --direct=1 --rw=randrw --rwmixread=90 --rwmixwrite=10 --bs=4k
--ioengine=libaio --iodepth=256 --numjobs=2 --time_based
--group_reporting --eta-newline=1 --runtime 12h --name=job1
--new_group --filename=/dev/nvme0n1

I noticed that while I am stressing it with fio the power consumption
of RAM is much less than if I use other stress utilities like intel
ptat or y-cruncher.

How I can run fio to use full power capacity of RAM? I tried to
increase numjobs but it didn't help.

Best Regards, Anatoly
