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. -- Vasiliy Tolstov, e-mail: v.tolstov@selfip.ru jabber: vase@selfip.ru
