Jeanfrancois,

I need to understand this more. The monitoring level for http-service
(under module-monitoring-levels) is turned off by default. So, there
shouldn't be any overhead related to monitoring on Grizzly side. Can you
please give me more details for the following statement.

    /"We have observed some performance regressions recently at runtime
    and one reason is the fact that the Monitoring & Management support
    (implemented as GrizzlyAdapter) are *always* registered as startup. "/


thanks
Prashanth
