Ralph Goers commented on LOG4J2-184: ------------------------------------ What platform and hardware are you running on? I added the test to Log4j 2 and ran it. Here is the output.

I > attached an small performance test which reproduces the problem. On my > machine the test takes approximately one second to complete. On the machine > at the customer project, I'm currently working on, it's even worse. > After analyzing this, I found out that the method > org.apache.logging.log4j.core.config.plugins.PluginManager.collectPlugins() > is called way to often which consumes most time of the initialization! -- This message is automatically generated by JIRA.
