Hi,

Just thought I'd mention that we found a pretty severe bug in Weld
Core while performance testing our application on Glassfish, that
makes creation of @ConversationScoped beans synchronized. Details are
here: https://issues.jboss.org/browse/WELD-1157

There's done some work on it in Weld Core trunk, but the issue is not
yet resolved.

This affects all versions of Glassfish 3.1.*, and also JBoss AS 7.

Regards,
Vetle
