Regarding ISPN-1786, I'd like to work with Sanne/Mircea on trying out the new UNICAST2. In my local tests, I got a 15% speedup, but this is JGroups only, so I'm not sure how big the impact would be on Infinispan.
If we see a big speedup, UNICAST2 and NAKACK2 could then be backported to a 3.0.4, and added to 5.1.1. However, I want to spend some time on testing UNICAST2, so this won't be available tomorrow...
