@SessionScoped @Stateful EJBs org.jboss.weld.ejb.api.SessionObjectReference.isRemove() several times per EJB invocation. The current implementation (as of [1]) of this is far too expensive, and results in several cache transactions per invocation.
Given that the purpose of this method is to throw a NoSuchEJBException, it should be sufficient to replace the current logic with a local variable.
