Joris van Heesch updated LOG4J2-2130:
-------------------------------------
Description:
Is there a significant difference between the following two configurations,
i.e. are there certain elements to consider in choosing one over the other?
1.
{code:xml}
<AppenderRef ref="out">
<ThresholdFilter level="anyValidLevel"/>
</AppenderRef>
{code}
2.
{code:xml}
<AppenderRef ref="out" level="anyValidLevel"/>
{code}
I looked at the class AppenderControl, and noticed that - to my surprise -
shouldSkip() checks isFilteredByAppenderControl() before isFilteredByLevel().
I also noticed both these methods are annotated with @PerformanceSensitive, but
I don't know if any of this is relevant.

I noticed the methods isFilteredByAppenderControl() and isFilteredByLevel() in
class AppenderControl are annotated with @PerformanceSensitive, but I don't
know if that's relevant.
