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 -version
java version "1.6.0_29"
Java(TM) SE Runtime Environment (build 1.6.0_29-b11)
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.

addition to results below the overall loading times of the web UI are much longer in 3.0.0
than in 2.2.1. I understand this is a good time to try and find if the performance can be
made better since the actual release of 3.0.0 is drawing near.
