Subject: | [Qemu-devel] Question about drive mirror |
Date: | Mon, 13 Jan 2014 23:44:09 +0800 |
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 storage, It is serial.
Now, I hope when it is writing the data to target storage ,we can send the
request
of reading data from source storage. Because of using
coroutine to do it ,there is
some troubles to achieve it. why not use Multi-thread?
Some one can give me some idea?
Thanks.
