Scott Deboy commented on LOG4J2-184:
------------------------------------

If someone works to reduce the calls to collectPlugins, be aware of the kinds of \
issues you can run into when plugins are cached - I had to fix this one:

> 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
> Attachments: Log4j2InitializationPerformanceTest.java
> 
> 
> 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!
