Hi!
Yes, I don't really see the startup time as an issue(Since it wasn't
drastically longer between the versions, IMO) but the operation time of
the deploy command/module and overall portlet latency should be shorter. I
could add my findings to the issue 6222.

Hi vdox,
Thank you for your testing on server startup and deployment time performance. I
think they are useful information for the community to trigger some analysis.
But before that, I also did some testing on my linux box(Ubuntu 10.04 x86_64).
Here are my configuration and results:

Java HotSpot(TM) 64-Bit Server VM (build 20.4-b02, mixed mode)
$ export GERONIMO_OPTS="-Djava.security.egd=file:/dev/./urandom"
G 2.2.1
1. First time startup: Startup completed in 16.641s seconds
2. Second time startup: Startup completed in 14.357s seconds
G 3.0.0-SNAPSHOT built on 20120620:
1. First time startup: Startup completed in 21.995s seconds
2. Second time startup: Startup completed in 15.935s seconds
So from the startup time results of mine, there is no big gap between 2.2.1 and
3.0.0-SNAPSHOT. But, for deployment time, there are some gaps saw from my
results as well.
About the deployment time issue, there is a known jira opened
(https://issues.apache.org/jira/browse/GERONIMO-6222), also there are some
improvements implemented in https://issues.apache.org/jira/browse/GERONIMO-5813.
