You run into problems with the garbage collector when the heap gets big: the bigger the heap, the longer it takes to compact. Azul has hardware support for their garbage collector which allows their compaction phase to run concurrently with the application, otherwise there'd be no way they could make use of the 768 GB ram their kit can scale to, unless striped across hundreds of JVMs. If you try to scale a normal collector to those heap sizes, you will see your stop-the-world collections jump from sub-second to minutes or even hours. > > -Stuart Sierra > > > -- Venlig hilsen / Kind regards, Christian Vest Hansen. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Clojure" group.
