I don't know yet, but after 2 days investigating I could identify NetworkManager service as a promoter of slow startup for Jboss AS 7.1.0.
While NetworkManager is running my jboss instance starts after 31 seconds. After stop the service this goes to normal 1.1 seconds.
I do not discovered what does this... but I figure out that It's because the network broadcasting to discovering another server.
Any idea???
thanks.
