[jboss-dev] Further profling: Where should I focus?

IIRC, from the JBoss AS meeting you already knew this but...
I was doing further times on no things in deploy/ and just deploying
what deployers don't have dependencies in deploy/.
12.5 secs with the deployer sorting optimization
10.6 secs if you remove AOPDependencyBuilder
8.8 secs if you remove AOPJoinputFactory
I did a profile after removing the AOP stuff and found that:
~35-40% is in creating classloaders with the majority of that time being
spent in discovering package names
~5-10% is in classloader.getResource()
But, talking to people, I'm pretty sure you already know this. The
question is, where can I help? I know work on VFS3 is going on. Should
I help there? I could also volunteer to work on removing AOP
dependencies that currently exist for some components.
After fixing those 2 problems, my bet is further reductions will be
found in optimizing resolveContexts().
