Try invoking your benchmark program with
{{-Xlog:class+init=debug:file=class.log}} and attach the results here. Based on
my own log file, I identified those above issues so far, though there could be
more.

> Key: LOG4J2-2795
> URL: https://issues.apache.org/jira/browse/LOG4J2-2795
> Project: Log4j 2
> Issue Type: Task
> Components: Core
> Affects Versions: 2.13.0
> Reporter: Romain Manni-Bucau
> Priority: Major
> Attachments: image-2020-03-06-08-58-21-169.png, log4j2.png
>
>
> Currently (2.13), LogManager.getLogger("xxx") takes ~600ms on a cold JVM by
> itself.
> For a logging framework it is likely way too much (by comparison a CDI test
> with classpath scanning takes ~50ms).
>
> This ticket is about trying to be faster (maybe by removing java
> serialization usage and reducing registry usage + reflection of plugins by
> generating java code?).
