---------------------------------
Hi Remko,
I work on a low latency trading system as well and would like a system property
to turn this feature on/off. At least it will give us a choice of going into
this with our eyes open!
Thanks.

> Key: LOG4J2-898
> URL: https://issues.apache.org/jira/browse/LOG4J2-898
> Project: Log4j 2
> Issue Type: Improvement
> Affects Versions: 2.0.2, 2.1
> Reporter: Steven Grossman
> Assignee: Remko Popma
> Fix For: 2.2
>
>
> Formatting a message can be an expensive operation (e.g. String.format) and
> it is undesirable for it to be done in the calling thread when using an async
> logger or appender.
> LOG4J2-763 moved this work to the calling thread. Would you consider
> bringing back the previous behavior via a config/system property?
