You will find that TCP is much faster when it comes to buddy replication, since
replication is unicast to target buddies rather than the entire cluster.

We are currently running 4 nodes with synchronous replication of rather large
data objects. (The replication is done within a transaction.)
The objects replicated are from 1k up to about 8k bytes large. These 4 nodes
currently handle up to 5000 events/second which would translate into 1250
repl
I think the largest clusters I've seen (with 1.4.x) has been with close to 50
instances, but that''s using async replication.
If you want sync replication, and you can guarantee session affinity, I'd
recommend buddy replication since this scales very well compared to total
replication.
Hopeful
