Re: [rules-users] Multi-threading inefficiency caused by static class synchronization?

I tried profiling my test program and found that all thread spent most of their time blocking or waiting for the same lock: org.drools.runtime.process.ProcessRuntimeFactory.getProcessRuntimeFactoryService() and org.drools.common.AbstractRuleBase.lock() examples: Thread-6 [WAITING] CPU time: 1s java.util.concurrent.locks.ReentrantReadWriteLock$WriteLock.lock() org.drools.common.UpgradableReentrantReadWriteLock.lowPriorityWriteLock() org.drools.common.UpgradableReentrantReadWriteLock.writeLock() org.drools.common.AbstractRuleBase.lock() org.drools.impl.StatelessKnowledgeSessionImpl.<init>(InternalRuleBase, KnowledgeAgent, KnowledgeSessionConfiguration) org.drools.impl.KnowledgeBaseImpl.newStatelessKnowledgeSession() java.lang.Thread.run() Thread-7 [BLOCKED] CPU time: 1s org.drools.runtime.process.ProcessRuntimeFactory.getProcessRuntimeFactoryService() org.drools.runtime.process.ProcessRuntimeFactory.newProcessRuntime(AbstractWorkingMemory) org.drools.common.AbstractWorkingMemory.createProcessRuntime() org.drools.common.AbstractWorkingMemory.setKnowledgeRuntime(InternalKnowledgeRuntime) org.drools.impl.StatefulKnowledgeSessionImpl.<init>(ReteooWorkingMemory, KnowledgeBase) org.drools.impl.StatelessKnowledgeSessionImpl.newWorkingMemory() org.drools.impl.StatelessKnowledgeSessionImpl.execute(Object) java.lang.Thread.run() -- View this message in context: http://drools.46999.n3.nabble.com/Multi-threading-inefficiency-caused-by-...
