(at least apparent, temporary success...)
Here is what worked for me:
1) Open Finder and navigate to this location:
HD > Library > Preferences > SystemConfiguration
2) Find the file named preferences.plist
3) Rename the file to preferences.plist.old (this preserves the data in case you need to restore the file for some reason)
4) Your system will then rebuild the preferences.plist file (not sure whether that happenes immediately or upon rebooting).
Let me know if this worked for you. This instantly solved my problem, and I'll keep an alias to that location on my desktop so I can repeat the process if the slow behavior reappears. Hopefully Apple will fix whatever is causing this problem with preferences.plist.
Have a great day!
AJDesignCo suggested renaming /Library/Preferences/SystemConfiguration/preferences.plist to force a rebuild of the file.

Thanks for the post. The only solution that has worked here( i.e. on my machine ) is the edit of /private/etc/auto_master as suggested by Snaggletooth_DE.
To try AJDesignCo's suggestion:
I backed out Snaggletooths_DE's suggestion and renamed per AJDesignCo's suggestion; it was not a solution here. My test is to simply open the Preview.app and use the File==>Open... menu. The dialog clocks ( spinning gear icon in lower left of dialog window ) and doesn't populate the files as per the original issue.
Please note the related discussion which is also solved by Snaggletooth_DE's workaround here
OK, I opened private/etc/auto_master in Text Wrangler, I put a # in front of /net and saved it.
Now what do I do? Close Text Wrangler? OR...
Where do i type --- sudo automount -vc? At the bottom of the file in Text Wrangler
OR in Terminal? If in termina... from what directory, the root? Home?
Where do i type --- sudo automount -vc?
When you see 'sudo' it mostly( commands can be put in scripts but there is no script building required here ) means a command to type in to the Terminal.app. 'sudo' requests temporary root authority which is required to execute the command ( which is the 'automount -vc' ).
btw: IMO older age doesn't necessarily imply computer ignorance; if it did I'd be really stupid. I agree the original post could have been clearer about where to use the editor vs. where to use the command.
So... This is what I typed in Terminal (with results) after saving the Text Wrangler file:
Last login: Wed Jan 29 04:55:39 on ttys000
sudo automount -vc
automount: /home updated
automount: /net unmounted
Is that the correct revisions to expect in terminal?
Am I done?
