Howard, perhaps you can do some tests for this to support the idea.

Oscar, You are right about this , I really forget PHP5's own garbage
collection, according  to the search results of google, the memory will
release when the function is close.

This is good, so you can have internal cache, to avoid duplicated query.


mmm...., Lifetype already has it's own DAO cache, I think this is not the
problem.
