Tushar created LOG4J2-90:
----------------------------
Summary: docs - tip for -server
Key: LOG4J2-90
URL: https://issues.apache.org/jira/browse/LOG4J2-90
Project: Log4j 2
Issue Type: Improvement
Components: Documentation
Environment: windows
Reporter: Tushar
Priority: Minor
Should add following to a FAQ or a page called 'improving log4j performance'
"I discovered that adding -Dmaven.surefire.debug="-server" to the command line
for SimplePerfTest yields performance similar to OS/X and Linux. The
implication is that Log4j2 is benefitting greatly from the Hotspot compiler (27
nanoseconds per iteration with the default and 2 nanoseconds per iteration with
-server). This probably also explains why, when I tried to to profiling with
YourKit making changes to eliminate what YourKit was finding as hot spots made
absolutely no difference as HotSpot was already eliminating them. However,
making the changes manually might bring the performance in -client mode closer
to -server."
But talk about adding it to your server java call. Also might be mentioning -
On windows server systems this happens automatically - I guess Java figured out
its being called on a server class environment. but it does make a difference
on a developer/ QA system
