Just to be clear (as you didn't show us the commands executed):
how did you execute the dd command 23 times?
In parallel, e.g. a background processes?

  dd if=/dev/sda of=/dev/sdb bs=1M &
  dd if=/dev/sda of=/dev/sdc bs=1M &
  ...
  dd if=/dev/sda of=/dev/sdw bs=1M &
  dd if=/dev/sda of=/dev/sdx bs=1M &
  ...

(Besides that I haven't seen such a system with so many disks... :)

If so, then that MUST be slowing down the system.

Have a nice day,
