For the same load, it takes around 8 minutes to start in Solaris (N5220,32GB RAM) compare to Linux (HP G8,32 GB RAM), which takes around 2.5 minutes. Time taken mostly by following log messages : EDT DEBUG [main] DeployersImpl - Added deployer org.jboss.deployers.vfs.deployer.kernel.BeanMetaDataFactoryDeployer@78c8c4d8 for stage Real . . . DEBUG [main] SaxJBossXBParser - Created parser: org.apache.xerces.jaxp.SAXParserImpl@5e402d95, isNamespaceAware: true, isValidating: true.. DEBUG [main] Domain - org.jboss.classloading.spi.dependency.Domain@3a784abe{DefaultDomain} add module VFSDeploymentClassLoaderPolicyModule ejb3.deployer        All the parameter e.g min and max heap size, number of files to be deployed are same. Could anyone let me know why is this difference?
