There are so many factors involved that I'd say it cannot be calculated.
The best strategy is to start with the default value of 4 and only fine
tune it based on the run times of real world queries.
If you experience problems with certain queries, post a short
description of your problem and EXPLAIN ANALYSE output to the
-performance mailing list.
