Make a backup and remove coloring rules and see what happens. Also check what happens if you remove all custom columns.

Just to see what happened, I deleted the rules in increments. I also realized that one of the custom columns, a non-template, had a color rule. These are the results:
Measurement used is how long it took to scroll right/left.
-No noticeable increase in speed between 16 and 38 color rules
-A small but noticeable increase at 15 color rules
-Larger increase in speed when I removed 3 color rules that had 'has this-but not this' conditions
-At 5 rules speed becomes acceptable with only occasional lag
-No noticeable lag with 1 color rule and 1 custom column w/color rule
Editing speed has increased as well, though I know the number of books I edit at any given time will have some affect on the processing speed. Processing 5 records is not the same as processing 500.
Thanks for the help in figuring this out.
I have to wonder if it might not be worth having a sticky with most common reasons for slowdown in Calibre. It might save a lot of headaches.
