Wouter Bancken commented on ARIES-1565:
---------------------------------------
Thx for the feedback [[email protected]].
We tried to apply the patch instead of our proposed changes. We did not notice
any improvements compared to the original Aries implementation (using utils
1.1.1).
Our implementation is giving an improvement of 74% during the installing phase
of our application.
> Performance Improvement: unpack subsystem artifacts to tmp folder to avoid
> directly reading from zip archive

> 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.
