Subject [jira] [Commented] (GERONIMO-6055) improve server startup time
Date Mon, 18 Jul 2011 13:45:57 GMT

Kevan Miller commented on GERONIMO-6055:
----------------------------------------

The fix for https://bugs.eclipse.org/bugs/show_bug.cgi?id=351438 can make a pretty big performance
improvement in some environments. There isn't an Equinox 3.7.1 integration build available,
yet (I'm told Wednesday). Once available, I'll plan on incorporating it into Geronimo.

> 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.
