---------------------------------------

Hello Ralph,
my machine is a Dell Latidude E6530 with an Intel Core i7-3720QM CPU @ 2.6 GHz and 8 GB RAM,
OS: Windows 7 64-bit

>             Project: Log4j 2
>          Issue Type: Bug
>          Components: Core

> 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!
