In Solaris, JBoss server takes around 8 minutes to start compare to around 2 minutes in Linux.

After profiling, it was found that "org.jboss.deployers.plugins.deployers.DeployersImpl.doInstallParentFirst" and "org.jboss.deployers.plugins.deployers.DeployersImpl.doDeploy" was taking the most time and in Solaris it is almost 4 times (~624 sec with profiler attached) than the same on Linux (~161 with profiler attached).
