Hi,

how to run scp command with lowest priority.

i used the following command in my script.

nice -n 19 scp @

when i do top, i see that scp is taking less cpu but ssh process is using almost 100% cpu.

28103 root 39 19 3600 1820 1428 R 97 0.0 0:07.42 ssh
28102 root 39 19 3076 864 728 S 1 0.0 0:00.14 scp

is there any way to set the prioprity to ssh process in this case?

thank you,

The real concern isn't that a process is consuming 100% of a CPU, but (1) is any other process suffering; and (2) what else is running.

Hello,

you can see that the scp process is sleeping (state S) and ssh is running (R). SSH and SCP are used together. Please take a look at the WA stats in top. 100% cpu load doesn't mean 100% work. ;) Maybe you system is waiting 80% of the time for IO.

Hope this helps.

Best regards,
Patrick
