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:

$ 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.

Hello,

 This was discussed with kevan to some extend on geronimo IRC channel on Freenode.

There seems to be a considerable performance hit between Geronimo 2.2.1 and 3.0.0. In 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.
