Subject [jira] [Commented] (EXTCDI-298) [perf] reduce overhead in ClassUtils
Date Wed, 11 Jul 2012 13:02:35 GMT

    [ https://issues.apache.org/jira/browse/EXTCDI-298?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13411454#comment-13411454

Mark Struberg commented on EXTCDI-298:
--------------------------------------

Can you please test now? I've at least removed the doPrivileged for you. It will now only
get executed if a SecurityManager is present.

For fixing the loadClassForName I would need a stacktrace. And the number of times this gets
called.

A cache as you did it is not possible since "org.mypackage.MyClass" might be different for
WebAppA and a WebAppB...

> As discussed with gerhard, i removed the #doPriviliged which improved the method execution
duration from 50ms to 0ms (30.000 invocations / request)
> I also added a class cache which improves loadClassForName from 62ms to 6ms for 9600
invocations.
