It's probably a little more efficient than separate Persistent handles unless the internal fields array is large but sparse (i.e., when only a fraction of the elements are in use.) > 2) What is limit on the number of internal fields? It should be large enough for your purposes. The theoretical limit is 2^30, the effective limit is what fits on the JS heap. -- -- v8-users mailing list [email protected] http://groups.google.com/group/v8-users --- You received this message because you are subscribed to the Google Groups "v8-users" group.
