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.
