Removing the binding manager is possible, and gave the following performance:
jbossweb-standalone: 4.5s / 80.5MB
jbossweb-standalone (no binding manager): 4.0s / 79.1MB
So the startup time gain is there, but memory usage is too high.
Overall, I don't think dropping the binding manager is a very good
idea.
SBM configuration should have its own schema[1]. Not sure what effect
that will have on boot time -- maybe good because the MC isn't dealing
with a bunch of beans it doesn't really need to know about; maybe bad as
another new set of xml parsing overhead is added.
Also relevant to the jbossweb-standalone numbers (but not too minimal)
is SBM is doing that XSL transform on server.xml. There's a JIRA to get
rid of that, although I'm not too happy about using system properties to
pass these values. We do it elsewhere though.
