Hi,everyone.
I tested the capability of drive mirror, I found the IO is low. Then I read the
code,
The code mirror_run() will call mirror_iteration() to read the size of buffer
data
from source storage, when the read callback ,and then in mirror_read_complete
()
write the data to the target
ading requestion. I think each iteration send the number of
data
should base on the granularity ,we can set the granularity is 1M. This way may
be
let the reading and writing is parallel.
