> h4. Description
> Aries copies ESA archives to a temporary zip file during the installation phase. Afterwards,
bundles are read directly from this temporary zip which has a large impact on the startup
performance of Aries applications. By unpacking the esa artifact into the temporary folder
it is unpacked only once. Subsequent reads for the bundles (jars) can be read directly from
the folder.
