Make sure you set the optimizer search depth in your my.cnf file if many of your queries have a large number of tables:

A 28 table query with some subqueries was taking about 20 seconds to complete with the default optimizer_search_depth value of 62.

After setting optimizer_search_depth = 0 (auto) the same query took 0.03 seconds.
