• [6.7.0-rc2] Very slow mover

    • Minor

    After update to 6.7.0-rc2 when moving data from SSD to array is very slow - about 10-16MB/s, switch back to 6.6.6 - speed went out to ~160MB/s.

     

    What I'm notice that n 6.6.6 process /usr/local/sbin/shfs uses about 12% of CPU but on 6.7.0-rc2 it use 2%.

    I've try to change Tunable (md_num_stripes), Tunable (md_sync_window), Tunable (md_sync_thresh) but speed remain very slow - right now I've switch back to 6.6.6.

     

    diagnostic from 6.6.6 and 6.7.0-rc2 attached below.

    I see you use encrypted xfs?

    I got the same speed, 10-15MB/s in write speed to encrypted xfs.... 

     

    I have a thread here:

     

     

    My guess is that this is the same problem.
