Not necessarily. Switches can do this fan-out more efficiently than any general-purpose machine could, so they're not going to get choked up, but the benefit's not that great either. The fact that one send from the client can consume resources on N server-side channels can also exacerbate problems like TCP incast collapse (in much the same way that similar "amplification" is the basis for many DoS attacks). Broadcast/multicast can still be useful for many things, but IMO not those that are both throughput- and latency-sensitive like we are. _______________________________________________ Gluster-devel mailing list Gluster-devel@xxxxxxxxxxx http://www.gluster.org/mailman/listinfo/gluster-devel
