Subject [jira] [Commented] (ARIES-1565) Performance Improvement: unpack subsystem artifacts to tmp folder to avoid directly reading from zip archive
Date Tue, 16 Aug 2016 14:31:20 GMT

    [ https://issues.apache.org/jira/browse/ARIES-1565?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15422794#comment-15422794
] 

John Ross commented on ARIES-1565:
----------------------------------

Unfortunately, I will not be able to take the lead on this. To whomever does, I suggest the
best solution would be to move the org.apache.aries.subsystem.core.internal.filesystem into
org.apache.aries.util. An Aries Util release would then be required prior to another Subsystem
release.

> 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.
