>Then, as I understand it, a lot of reconnection in the ring cannot create even temporary but major problems for performance. And in general this optimization will change practically nothing. Or am I missing some things?
I am afraid I did not understand this at all. Please elaborate. I did not suggest any reconnections or ring rebuild. All I suggest is to control over ring building process with arcs. And, yes, proper built ring should reduce latency of ring messages IMO. --Yakov
