Indeed an actor model for Vala would be a sweet deal. Perhaps an actor model could even replace a "mainloop concept" in the Dova profile (this is just me rambling :-)). Looking at your code I see two major issues that will prevent you from scaling into millions of actors: * No work stealing * The mailboxes are implemented as async queues living on a per-actor basis A fully scalable actor model needs a work stealing thread pool and for the task queues to live per-thread in that pool, and not per-actor. This way you will have extremely low lock contention. -- Cheers, Mikkel _______________________________________________ vala-list mailing list vala-list@gnome.org http://mail.gnome.org/mailman/listinfo/vala-list
