[jboss-user] [JBoss Cache: Core Edition] - JBoss Cache performance looks pretty poor :(
Hi,
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"?>
jboss:service=Naming
jboss:service=TransactionManager
org.jboss.cache.transaction.GenericTransactionManagerLookup
READ_COMMITTED
false

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