-----------------------------------
This was done using our proprietary code which cannot be shared. We are in the
process of creating and demonstrating the sample application, will update soon.
In our application ,we are using RollingFileAppender and sync logger. We
identified this issue during our performance test. The performance was affected
after we upgraded from 2.11.0 to 2.13.0.
