Description Andrig T Miller 2013-10-22 21:01:33 UTC 
Description of problem:

https://issues.jboss.org/browse/WFLY-2021

Version-Release number of selected component (if applicable):

EAP 6.2

How reproducible:

N/A

Steps to Reproduce:
1.
2.
3.

Actual results:


Expected results:


Additional info:

This is a performance enhancement which shrinks the memory footprint for EJB applications, and should provide benefits in CPU consumption too, but mostly reduces the memory footprint.

The link in the description is the issue upstream, and this has already been merged.

We would like to put this into EAP 6.3.

Also, EJB is no longer a separate component, so this just needs to be back ported and merged into the core AS code base.
Comment 1 Andrig T Miller 2013-10-22 21:02:36 UTC 
Changed the type to enhancement, as this is a performance improvement, not a functional bug.
Comment 3 Dimitris Andreadis 2013-10-24 18:27:13 UTC 
Assigning jpai EJB issues to david.lloyd. Please re-assign to Cheng or others as needed.
Comment 4 David M. Lloyd 2013-10-25 02:55:34 UTC 
Assigned to Stuart since he's actually working in this area right now.

Stuart Douglas <stuart.w.douglas> made a comment on jira WFLY-2021

Done. Memory usage reduction was quite dramatic. For a simple test I ran 30k SFSB instances dropped from 350mb of usage to 20mb.
