[jboss-jira] [JBoss JIRA] Commented: (EJBTHREE-2042) Investigate performance issue related to use of @SecurityDomain on EJB

Husgaard commented on EJBTHREE-2042:
------------------------------------
I just discussed this with Rémi Nodet, and this application has a lot of calls from
session facade beans to EJB2 entity beans. Here the PreSecurityInterceptor is in the
interceptor chain, and I see lots of possible optimization here.
In particular some low-hanging fruit (trivially easy optimization): In
PreSecurityInterceptor.java we have the following lines in different places:
log.trace("SecurityIdentity="+SecurityActions.trace(si));
log.trace("Going to the SecurityInterceptor with
SC="+SecurityActions.trace(currentSC));
log.trace("establishSecurityIdentity:SecCtx="+SecurityActions.trace(newSC));
The calls to the SecurityActions.trace() involve an expensive
AccessController.doPrivileged() to build the string returned, even when logging is not at
trace level.
Investigate performance issue related to use of @SecurityDomain on
EJB

Key: EJBTHREE-2042
URL: https://jira.jboss.org/browse/EJBTHREE-2042
Project: EJB 3.0
Issue Type: Task

A user has reported that the use of @SecurityDomain shows a relatively poor performance
(even when a @PermitAll) is applied to the bean. See the referenced forum thread for
details.
Although, it can't be guaranteed that the performance of a bean method invocation
with a @SecurityDomain will be same as that without a @SecurityDomain, the difference in
the timings as reported in that thread looks a bit too high. This JIRA is to track to
investigate the issue and see if there's any genuine performance bug.
