I think this jar is a realistic example of a pbs server jar 'polluted'
with unecessary files since it was created using the Eclipse export
mechanism that includes all dependend projects:
http://129.206.117.40:2222/test/test.jar, size: 30 MB

Extracting this jar takes a very long time. My performance tests do
not include extracting the jar but I assume that the content of that
jar is already available in a single folder.
I don't know enough about the build process used at the moment but I
guess all the files, including those for the pbs server are available
at some point in a single folder? Is this the case?

Starting with a folder containing all files: .class, images, .dll,
.properties, etc.

Results:
Dependency analysis ~1 sec.
Creating a jar ~3 sec. (size: 1 MB)
Compressing this jar (pack200+Gzip) ~1 sec. (size ~350 kb)

The pbs server should therefore be below 500 kb.

Cheers,
Dieter
