I am not sure for friendliness of possible dd interpretations for
new
leaky bucket mechanism, as its results can be a little confusing even
for fio (all operations which are above the limit for long-running
test will have 250ms latency, putting down score numbers in most
popular tests like UnixBench), also w/o sync options these results are
almost meaningless. May be fio with direct=1|fsync=1 (for fs) will
give a more appropriate numbers in your case.
My fail. I'm forget to add iflag=direct to dd. Now all fine i get is
around 20 MB/s which compared to 5000 iops.
Thanks.
