First off, I want to thank all of you that have given me suggestions.
It really is appreciated. Here is the update.
I backed up all of my data to an external drive and did a complete
re-installation of the OS, then resorted the data. The first few tests
of the database were fine, but after waiting a few hrs and trying again
I saw the long open time again. At this point I exported all of the
data to csv file and to sql file. I recreated the database file with
a table where I definitely specified the ID as primary key. I imported
the csv data. I tried importing the sql but I aborted the process after
an hour, as the progress was really poor. The csv import was done in
under a minute. Now open times are a consistent 7 seconds with the
load of the entire database into a variable is 4 seconds. I did all of
this last night and I am seeing the same behavior this afternoon.
So my take on this is that I did have a systems issue that was slowing
things down, but I also think that the database was not configured
correctly initially.
Anyway, I am operational again. And thanks again for your kind help.

This is a good opportunity for all of us to remember that portable
large-capacity hard drives are dirt cheap compared to the cost of lost data.
A USB 3.0 1TB drive can be picked up at the corner market for about US$60,
and a 2TB drive for under US$85.
I know everyone here already has multiple redundant daily backups anyway,
but there was a time many years ago when I didn't, and I paid for it dearly.
Now I have one copy of everything in the cloud, three in my office, and
three at home which are rotated through the office so at least one of those
offsite backups is never older than 24 hrs.
With an rsync script backing up is super-fast and as easy as typing a single
word in Terminal. Yes, I also use Time Machine, but relying on any single
backup isn't enough; drives fail, software fails, archives corrupt, merde
happens. rsync takes only a few minutes to learn and can move large amounts
of data with ease anywhere, a perfect compliment to other backup systems for
multiple redundancy.
Far more than needed? Exactly. Disks are cheap, but time is the rarest
commodity in the universe.
Last year my MacBook Pro started acting wonky so before I ran any
diagnostics the first thing I did was make a full backup. Good thing:
the mobo died half an hour later. I just copied the files I needed to
another machine and was back to work in minutes.
