sshd high CPU when rsyncing

Question

I am using the following rsync command:
&nbsp;
rsync -avW /data/Media/* /eda2/Media2/ --progress --stats --remove-source-files&nbsp;
&nbsp;
when I do, I see:
&nbsp;
 PID USER      PR  NI    VIRT    RES    SHR S  %CPU %MEM     TIME+ COMMAND
 4370 root      20   0  314764  14256   1936 S 196.3  0.7 196:22.58 sshd
 4381 root      20   0  138068   4024    740 S  27.5  0.2  32:01.93 rsync

Is that sshd cpu usage normal?

Hi joe_schmo

&nbsp;

Using RSYNC uses lots of CPU and using it over SSH would also make sshd use a chunk too. The process tunnels RSYNC on SSH so we can expect this kind of CPU usage is normal.

&nbsp;

Hope this helps!

&nbsp;

This command doesn't seem to be tunneling over ssh, so I don't understand the sshd overhead.
&nbsp;
This is a local transfer, correct?&nbsp; (/data and /eda2 are two volumes on the same ReadyNAS?)&nbsp;
Is this the full command (no -e ssh)?&nbsp;&nbsp;
