Hi,
I have found the same results on 2 different systems:
It seems to peak at ~350MiB/s performance on mdadm raid, whether
a RAID-5 or RAID-0 (two separate machines):
The only option I found that allows it to go from:
10737418240 bytes (11 GB) copied, 48.7335 s, 220 MB/s
to
10737418240 bytes (11 GB) copied, 30.5425 s, 352 MB/s
Is the -o nodelalloc option.
How come it is not breaking the 350MiB/s barrier is the question?
Justin.
