Re: [jgroups-users] JGroups 3.4.0.Beta1

[Karim A. <kar...@gm...>]

Hi Bela,

Thanks for these optimizations.

I used this version (3.4.0.Beta1) and created a large scale JGroups cluster
with 1115 nodes.

If your are interested, I can give you further details about configuration
and test conditions.

Best regards.
