IIRC Carsten Dominik made the following observation: org tables are
extremely slow if they are used as workbooks/spreadsheets and there are
many entries (many is undefined). He recommended that a spreadsheet
program in such situations.
I learned that the hard way when I had one table - four columns, three
simple addition formulas with about 1,000 entries. It seemed an eternity
before the addition was completed.
