Did a quick experiment with removing some "optional" items from the
Tomcat assembly (results are using Java 5 on a 2.4GHz Core 2 Duo system
running openSUSE 11.0.)
The current geronimo-tomcat6-javaee5 tar.gz assembly for trunk I built
last night is 87.1 MB, takes 23.5 secs to start and uses 170MB RAM.
If we removed the following from the assembly and made them optional
plugins that the user can install if they want these features -
- MConsole
- Dojo
- Debug Views
- Plan Creator
- CXF
Then the tar.gz drops to 79.5 MB, takes 19 secs to start and uses 155MB
RAM. About 2.8 secs was for the Monitoring Console and agent support,
with another 0.5 secs being the Plan Creator and Debug Views.

Someone mentioned on another thread(s) awhile back that they would like
to see us reduce the server footprint and startup time for 2.2.
One way to do this (mainly for footprint) would be to start moving some
of the plugins that are not required for a JEE5 runtime out of the
server assemblies we create and made available as optional user
installable plugins (from the normal maven repos.)
I'm proposing that we remove the following from the default server
assemblies as a start:
- Debug Views
- Monitoring
- Plan Creator
We can either update the Welcome Portlet to mention these are available
from the Plugin repo or create a "placeholder" portlet for each that
describes what the optional plugin provides along with a link to install
the full version. Also, the testsuite would be updated to install the
required plugin before any tests are executed against it.
Thoughts?
