Hello.

I would like to ask a question.(I am poor at English.)

I am developing application.

My application uses Version2.11 of JGroups. (And Java version1.6.)

In clustering of three servers, it is satisfactory for processing performance.

However, if four sets, five sets, and clustering increase, processing will deteriorate rapidly.

It seems that synchronous processing of cash between servers takes time.

I would like to design to carry out the scale-out of the application.

However, three or more sets of clustering are not made for this problem.

Please let me know what is known.
