You should know the answer to the following questions before you start.
What effect does increasing the block size from 8192 to 32768 have?
What percentage of disk i/o capacity does a step take? You can use sar to determine this. and from this you should be able to calculate the number of megabytes per hour that you can process at a given disk usage threshold.



Pick two or three of the largest tables and manually run them in series. Record the wall clock time. Run them again in parallel and record the wall clock time. If you have other users on the system while you are running this experiment. record the response times when running serial and parallel.

DESCRIPTION

       systemd-ask-password-console.service is a system service that queries the user for system passwords (such as hard disk encryption keys and
       SSL certificate passphrases) on the console. It is intended to be used during boot to ensure proper handling of passwords necessary for
       boot.  systemd-ask-password-wall.service is a system service that informs all logged in users for system passwords via wall(1). It is
       intended to be used after boot to ensure that users are properly notified.

       See the developer documentation[1] for more information about the system password logic.

       Note that these services invoke systemd-tty-ask-password-agent(1) with either the --watch --console or --watch --wall command line
       parameters.
