Greetings to all,
"Fix Report" follows:
Having followed the instructions generously provided above, I have found 
no difference in start-up performance, i.e. "swap" does not 
automatically come on.
No change in startup performance.
Thank you for the suggestions though!
I continue to research the matter.
Re-installation is an option, although not a desirable one.
