Even the simplest deployments consistently take 10-12s on my reasonably powered MBP. For the topics integ, which does nothing more than require immutant.messaging and start a single topic in its immutant.clj, here's the log output:
13:33:32,619 INFO [org.jboss.as.server.deployment] (MSC service thread 1-3) JBAS015876: Starting deployment of "topics.clj"
13:33:45,668 WARN [immutant.xa.transaction] (MSC service thread 1-1) Patching java.jdbc 0.2.x to set transaction strategy
13:33:46,530 INFO [org.hornetq.core.server.impl.HornetQServerImpl] (MSC service thread 1-1) trying to deploy queue jms.topic./topic/gravy
13:33:46,795 INFO [org.jboss.as.osgi] (MSC service thread 1-2) JBAS011907: Register module: Module "deployment.topics.clj:main" from Service Module Loader
13:33:46,981 INFO [org.jboss.web] (MSC service thread 1-1) JBAS018210: Registering web context: /topics
13:33:47,009 INFO [org.jboss.as.server] (HttpManagementService-threads - 1) JBAS018559: Deployed "topics.clj"
That WARN is coming from the require of immutant.messaging, so something prior to that is taking an awful long time.
