I can account for a couple differences between minimal and
jbossweb-standalone:
1) conf/jboss-service.xml in minimal does not include this huge addition
to the server classpath:
<classpath codebase="${jboss.common.lib.url}" archives="*"/>
Ok, I think I could remove some of the JAR from the CL, but far from
everything. So not sure about the net gain here
Adding that to minimal increases it's startup time for me from ~
6.4s to
~ 6.8s.
It's sort of custom built, so I had to buy it myself. It's pretty cheap though.
BTW, Dimitris, I want a machine like his 2.6s one. ;-)
2) The ServiceBindingManager config in minimal is just an empty
placeholder; in jbossweb-standalone it's the real thing. Putting that
one in minimal increases its boot time to ~ 7.2s.
Removing the binding manager is possible, and gave the following performance:
jbossweb-standalone: 4.5s / 80.5MB
jbossweb-standalone (no binding manager): 4.0s / 79.1MB
So the startup time gain is there, but memory usage is too high.
Overall, I don't think dropping the binding manager is a very good
idea.
