CAS bootstraps a number of services and can be slow to reach an operational state. I ran into another situation which contributed to a very slow load time, but I don't if it would apply to you. We use local VMs with vagrant and VirtualBox for development. I found that when I ran a new WAR file from a location that was shared from my host filesystem into the VM, the load time was extremely slow. Simply copying the WAR to the local file system made a dramatic difference. Could your filesystem be something to look at?
