I found some solution: The memoizable library that can serialize/deserialize object in memory or in a file. then the Weakrefs of ruby stdlib, in particular i've found this link: http://eigenclass.org/hiki.rb?weakhash+and+weakref For performance reasons and whatever what do you advise me to do? examples,solutions, useful link? thank you :tele
