[jira] [Commented] (EXTCDI-298) [perf] reduce overhead in ClassUtils

["Mark Struberg (JIRA)" <de...@myfaces.apache.org>]

    [ https://issues.apache.org/jira/browse/EXTCDI-298?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13411441#comment-13411441 ] 

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

please don't cache classes. This has a huge impact. The easy solution is to not run in a doPrivileged block if no SecurityManager is available. Will fix this.

> 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.
