[jboss-user] [JBoss Cache: Core Edition] - JBoss Cache performance looks pretty poor :(

I'm evaluating various java-based distributed caching solutions: JBoss Cache (version 2.1.1 GA), EHCache, and TerraCotta.
My data size is 10 million objects and using 3 nodes each with 10GB HeapSize.
So far EHCache is proven to be very fast, reliable (never goes down for many tests iteration for many hours), and uses small footprint. I can  do 40,000 puts/second on 3 nodes cluster.

Ok - I'm here to ask about JBoss Cache.
Putting 1 million Objects (small ones - consisting of 3-4 Strings), the rate is like 2000/second, and once I start the second node the second node just dies right away giving me this error:
org.jboss.cache.CacheException: Unable to fetch state on startup

The memory usage is way too high. 1 million objects give require 2GB of Heap (after I GC'd of course and watched this from JConsole).

They way I'm using the tree cache is I create *all* 1 million objects on their own node/fqn. So I have ROOT/Object-1, ROOT/Object-2 ... ROOT/Object-1000000.

My configuration file:
<?xml version="1.0" encoding="UTF-8"?>





            <UDP mcast_addr="" mcast_port="48866"
                 ip_ttl="64" ip_mcast="true"
                 mcast_send_buf_size="150000" mcast_recv_buf_size="80000"
                 ucast_send_buf_size="150000" ucast_recv_buf_size="80000"

            <FRAG2 frag_size="8192"/>
            <pbcast.GMS join_timeout="5000" shun="true" print_local_addr="true"/>

I believe I'm missing something here so be great if anybody can help.
Thanks a lot.
