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. > Using less files for HornetQ would be ok for development.. 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. > but we don't > have a production profile where users would take benchmark results. 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. -Jaikiran > I believe other projects would have the same issue as well.
