Ok, done. This is the same Infinispan build, but using JGroups bbc128:

Done 880,969,860 transactional operations in 24.71 minutes using 5.1.0-SNAPSHOT
  875,033,689 reads and 5,936,171 writes
  Reads / second: 590,216
  Writes/ second: 4,003

Looks like a bit slower - confirming the figures I had two days ago.
Anyway my purpose with the comparison was just to proof the latest
patches in Infinispan where going in the correct direction, so I'm
intentionally not changing JGroups versions yet.

If you commit it on an experimental branch, I'll give it a preview run ..
Cheers,
