Paul Ferraro commented on ISPN-4162:
------------------------------------

After our last F2F meeting, I was under the impression that this optimization was not in place.  I guess I was mistaken.  I guess we can close this then?

> It would be nice if DIST could conditionally use multicast instead of multiple unicasts when the number of owners to which to send a given command >= the size of the cluster.  In fact, we could probably come up with some configurable ratio of the size of the cluster (perhaps as high as 50%?), above which it is more optimal to use multicast vs multiple unicasts.  This would optimize the use of DIST in smaller, dynamic clusters.
> With such an optimization in place, REPL would be completely obsolete.
