Ralph Goers commented on LOG4J2-2909:
-------------------------------------
I have JProfiler 11.1.4 installed on my MacBook Pro. No matter how I look at
this snapshot I can't find anything useful in it. The only thing I can tell is
that you have lots of logging going on from all over your application. Is it
possible you can get a trial of YourKit and try using that for profiling? I am
just not seeing anything inside of Log4j other than logger.info and I know that
method has almost zero overhead.
Scheduling a meeting is possible. What timezone are you in? I am based in
Arizona so I am UTC-7
