             Summary: the performance for the log4j initialization needs to be improved
                 Key: LOG4J2-184
                 URL: https://issues.apache.org/jira/browse/LOG4J2-184
             Project: Log4j 2
          Issue Type: Bug
          Components: Core
    Affects Versions: 2.0-beta4
            Reporter: Andreas Rytina


The initialization of Log4j 2.0 beta4 via an InputStream takes too long. 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!
