Erick Erickson commented on SOLR-12055:
---------------------------------------
Forgot to attach the rollback patch last week, it's there now. People can
probably ignore it.
I'll be starting this up again today locally, although anyone with knowledge
here please chime in.
> Enable async logging by default

> When SOLR-7887 is done, switching to async logging will be a simple change to
> the config files for log4j2. This will reduce contention and increase
> throughput generally and logging in particular.
> There's a discussion of the pros/cons here:
> https://logging.apache.org/log4j/2.0/manual/async.html
> An alternative is to put a note in the Ref Guide about how to enable async
> logging.
> I guess even if we enable async by default the ref guide still needs a note
> about how to _disable_ it.....
