> 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
> Fix For: 2.0-beta2
>
>
> 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
