Really would like to have that fun but I'm evaluating it for production use in the next 3-4 months. I downloaded 2.2 CR6 and changed the: StateRetrievalTimeout=600000 (5 minutes) pbcast.GMS join_timeout="60000"
I haven't changed my code to spread objects further down the tree. BTW, this seems odd or I may have missed something, but shouldn't the cache system do this spreading behind the scene? Depends on the key of the objects to cache, it could be difficult to balance the tree. And to know the "path" before I can do a "get". It's much simpler to do straight "key" lookup. (just my 2cents) Back to performance and memory. It's stable now with 2 nodes. The rate of my insert is increased from 2000/s to 4000/s. This is one at a time and SYNC that is 0.25ms/operation which is very good and multithreaded should increase this by a lot (I hope). But the memory consumption is still very high (maybe b/c I put everything right under "root"). 4GB for my 1M objects | num #instances #bytes class name | ---------------------------------------------- | 1: 16000897 768043056 java.util.concurrent.locks.ReentrantLock$NonfairSync | 2: 16000820 768039360 java.util.concurrent.ConcurrentHashMap$Segment | 3: 16000820 528806520 [Ljava.util.concurrent.ConcurrentHashMap$HashEntry; | 4: 43792 323829848 [I | 5: 2021461 153453344 [C | 6: 1002432 152294120 [Ljava.util.HashMap$Entry; | 7: 1000052 152007808 [Ljava.util.concurrent.ConcurrentHashMap$Segment; | 8: 1000002 88000176 org.jboss.cache.UnversionedNode | 9: 2016545 80661800 java.lang.String | 10: 1000002 80000160 org.jboss.cache.invocation.NodeInvocationDelegate | 11: 1000052 72003744 java.util.concurrent.ConcurrentHashMap | 12: 1000002 72000144 org.jboss.cache.lock.NonBlockingWriterLock | 13: 1002113 64135232 java.util.HashMap | 14: 1001773 48085104 java.util.HashMap$Entry | 15: 1000281 48013488 java.util.concurrent.ConcurrentHashMap$HashEntry | 16: 1000002 48000096 org.jboss.cache.lock.IdentityLock | 17: 1008529 40619728 [Ljava.lang.Object; | 18: 1000771 40030840 java.util.ArrayList | 19: 1000004 40000160 org.jboss.cache.Fqn | 20: 1000002 40000080 java.util.RegularEnumSet | 21: 1000000 40000000 com.ssn.jbosscache.Meter (my objects) | | I constantly see: | | 2008-07-23 10:09:47,929 [Incoming,JBossCache-Cluster,10.57.132.54:38174] WARN org.jgroups.protocols.pbcast.NAKACK.handleMessage - 10.57.132.54:38174] discarded message from non-member 10.57.132.53:33187, my view is [10.57.132.54:38174|0] [10.57.132.54:38174] | | View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4166221#4166221 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4166221 _______________________________________________ jboss-user mailing list jboss-user@lists.jboss.org https://lists.jboss.org/mailman/listinfo/jboss-user
