[jboss-user] [JBossCache] - What replicates in JBC 1.4?

[jorgemoralespou_2]

Hi,
We have a large application, with large amount of data stored in cache. For some data, we store it as nodes, for some other data, we store it as attributes, in order to find a good compromise between number of nodes, data in each node. We use SYNC_REPL to replicate data between our 2 node cluster, and use multicast for replication.

I would like to know?


For a 10000 atribute node, what data is replicating when we change on of the attributes? Is it replicating the whole node data, or only the changed attribute?
What is faster, access to a 10000 attribute node, or access to 10000 nodes single attributed?
Would REPL_ASYNC signify a performance gain?
Would the be deadlocking issues when more threads access cache. It seems our application doesn`t scale clients very well. (I have already seen http://www.jboss.com/index.html?module=bb&op=viewtopic&t=122400 which I gues will not be backported to 1.4)
Is it better to set up TCP replication?
Is there any performance tunning guide?


Thanks, like always.
