I did it locally, can send you a pull request.
But to clarify: this would disable clustering! Do you really want
that? the first option is safer, I'd just change the IndexManager.
I can send you a pull request for both variations of the
configuration, just let me know which file it is I have to patch: I
tried to look into the repository for capedwarf-jboss-as, but the
configuration file in there seems quite different than the one in
CapeDwarf blue distribution. So I'm not sure if I'm looking in the
right place, or maybe the wrong branch?

General optimisation, the usual stuff: profile it, rinse and repeat. I
didn't look at details but I remember a priority would be to optimise
some HashMap lookups for internal services and components.

It's probably better to try tuning the CacheStore then, but you'll
always be quite slow as CacheStore(s) significantly slow down
You should also ask yourself if the CacheStore is really needed.
