[jboss-as7-dev] Fwd: jboss-el-api_2.2_spec APIs and Wildfly

----- Forwarded Message ----- From: "Stuart Douglas" <sdouglas(a)redhat.com&gt; To: "Shelly McGowan" <smcgowan(a)redhat.com&gt; Cc: "Remy Maucherat" <rmaucher(a)redhat.com&gt; Sent: Thursday, July 18, 2013 1:00:15 AM Subject: Re: jboss-el-api_2.2_spec APIs I created this class to address a fairly major EL performance issue (that factory finder is invoked on every EL invocation, and it is both slow and acquires locks, which cause lots of contention). We may need to do a similar performance fix in the org.glassfish EL module, but I am not really sure. Assuming the problem still exists and we remove this fix our JSF performance will drop considerably.
