------------------------------------
Summary: Investigate ThrowableProxy performance
Key: LOG4J2-2391
URL: https://issues.apache.org/jira/browse/LOG4J2-2391
Project: Log4j 2
Issue Type: Task
Affects Versions: 2.11.1
Reporter: Carter Kozak
I've noticed when applications get into a state where they log more exceptions
than usual (e.g. network connectivity issues) thread dumps contain many threads
working inside of ThrowableProxy, loading classes.
A simple jmh benchmark of a pattern layout writing to disk with a message and
throwable appears to write about 160,000 events/second using a throwable, and
2,000 events/second using ThrowableProxy.
I will investigate to understand where the substantial difference is coming
from, and clean up the benchmarks to add to the log4j2 benchmarking module.
