This is my fio job: $ modprobe brd rd_size=10485760 rd_nr=1 $ fio --name=brd --rw=<type> --size=10G --io_size=100G --cpus_allowed=1 --filename=/dev/ram0 --direct=1 --iodepth=64 --ioengine=io_uring --loop=8 I ran the above job four times and averaged it as I noticed some variance. I ran the test in QEMU as we were using a block device where the backing storage lives in RAM.
