Description

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.
