There is a setting (can't remember it exactly) to tell ivy whether to
download ivy.xml files every time, or to use the previously cached one (if
the version has not changed). If you don't expect your ivy.xml files for the
same revision to change then this should help.

Also, using JAR files right out of the cache (e.g. for when building a
CLASSPATH) instead of copying them saves disk copies.

Modules contain configurations, not the other way around.

If by "module" you meant "artifact" then the answer is no, the artifact will
only be included once even if it is listed in multiple configurations.
