Slightly related, I wonder if Manik's comment is still true:

if at all possible, try not to use JGroups' ANYCAST for now.
Multiple (parallel) UNICASTs are much faster.)

Intuitively it shouldn't be true, unicasts+FutureCollator do basically
the same thing as anycast+GroupRequest.

Yes, this is outdated and may not be an issue with JGroups 3.x anymore. The problem, IIRC, was that ANYCAST would end up doing UNICASTs in sequence and not in parallel.
