Subject [jira] [Created] (GERONIMO-6055) improve server startup time
Date Fri, 08 Jul 2011 04:28:16 GMT
improve server startup time
---------------------------

                 Key: GERONIMO-6055
                 URL: https://issues.apache.org/jira/browse/GERONIMO-6055
             Project: Geronimo
          Issue Type: Improvement
      Security Level: public (Regular issues)
    Affects Versions: 3.0
            Reporter: Kevan Miller


3.0 server startup has gotten kind of slow. Time to see if we can boost it, a bit.

I've made some measurements of server startup time using YourKit Java Profiler (which I think
is a great memory and performance analysis tool). If anybody is trying to use it with Geronimo,
you need to update etc/config.properties in order to run YourKit with Geronimo 3.0. Add "com.yourkit.*"
to the org.osgi.framework.bootdelegation setting.

There are a few surprising hot spots. There may be some improvements that we can suggest to
the Equinox project. However, I think there are some improvements that we should be making,
also...

I'll attach some screen captures that should illustrate some of the issues.
