IMO, that approach is wrong. For doing any performance testing, the user 
should be aware of what configs they are testing against. Such users are 
expected to tune/change configs before doing the tests. Also IMO, such 
users aren't many, compared to developers who just want to see their AS 
up and running in minimal possible time.

IMO that should be OK. After all, it's a internal impl detail of the JMS 
provider, which not many developers want to change while developing 
their application. Of course, in production, it's a different 
perspective altogether.

Talking from a community edition (JBoss AS) point of view, although we 
do not have a production profile for benchmarking, there are some wiki 
articles or even project specific docs which talk about tuning the 
configs for production use. So as long as we document this somewhere, I 
guess it's worth changing the HornetQ configs for AS to allow the server 
to start in minimal possible time.
