    [ https://jira.jboss.org/browse/WELD-711?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12568910#comment-12568910 ] 

Martin Gencur commented on WELD-711:
------------------------------------

This commit (or series of commits) had crucial impact on performance, but the bad way. The stress test now reaches only 4500 sessions while before it reached 10900 sessions. I compared these two builds: 1) weld/master with head=7c9120c263 and 2) the WELD-711 branch from https://github.com/pmuir/weld-core with head=610e3d977b, both were tested with JSF 2.0. The resulting statistics are as follows: https://hudson.qa.jboss.com/hudson/view/Weld/job/perf-weld-numberguess-stress-single/132/artifact/report/log.txt , https://hudson.qa.jboss.com/hudson/view/Weld/job/perf-weld-numberguess-stress-single/135/artifact/report/log.txt

> Using the seam-faces module @ViewScoped extension, when the object is destroyed by Contextual.destroy, weld still references an instance, avoiding being garbage-collected.
> Pseudo Code: 
> 	Contextual contextual = ...
> 	Object instance = ...
>         CreationalContext creational = ...
> 	contextual.destroy(instance, creational);
