Matt Sicker commented on LOG4J2-2795:
-------------------------------------
I should note that I've also made several static init blocks lazy, though not
all of them (some looked fairly trivial), and many of those will still end up
being executed once you start logging. Try out master again and let me know
what you think.

> 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?).
