Kevan Miller commented on GERONIMO-6055:
----------------------------------------
Some of the data from the .png attachments seems a bit skewed. So, I
instrumented some code to look at where we're spending some time... Here's some
of the results:
_Startup completed in 19.411s seconds_
Of that time, we spent nearly half of that time in
o.a.g.bval.ValidatorFactoryGBean.createDefaultFactory() and
o.a.g.tomcat.TomcatContainer.addContext() (following times are in milliseconds):
_ValidatorFactoryGBean.createDefaultFactory() time: 249, Cumulative time: 4064,
Average: 254_
and
_TomcatContainer.addContext() time: 1704, Cumulative time: 5454, Average: 495_
Of the addContext() time, we spent nearly all of the time in the following 2
methods during the addContext() processing:
_GeronimoStandardContext.setContextProperties() time: 321, Cumulative time:
3266, Average: 296_
_GeronimoStandardContext.startInternal() time: 1382, Cumulative time: 2125,
Average: 193_
This final startInternal() call occurred during the start of uddi-tomcat.

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

> 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.
