Did a quick round of profiling. Now that the admin-console deployment is 
lazy and separate from the server bootup, it was easier to find out 
what's taking time.

For first access (*not* the login), turns out, the WARAnnotationDeployer 
spends almost 41 % percent of the time processing the war - mainly in 
getClasses() which starts looking for classes in the war file for 
annotation scanning. The admin-console.war/WEB-INF/lib has jar totaling 
to10 MB in size. I remember, there was discussion to add 
metadata-complete, to the web.xml of this war. I don't see it in the 
web.xml. Also, adding that hadn't shown any performance improvements. 
Looking at the WarAnnotationMetaDataDeployer.deploy(...), or other 
methods in there, i don't see any check for metadata-complete.

I'll see if there's some quick fix for this that might improve performance.

As for the time taken to login, i haven't looked at the profiler results 
yet.
