[ http://jira.qos.ch/browse/LBCLASSIC-175?page=com.atlassian.jira.plugin.syste... ] Torsten Juergeleit commented on LBCLASSIC-175: ---------------------------------------------- Please keep LogEvent.prepareForDeferredProcessing()s current behavior of only preparing the "cheap" stuff like thread name and MDC. The "expensive" stuff (mainly the caller data) can be easily prepared by calling LogEvent.getCallerData() if really wanted. This is what the suggested implementation of an AsyncAppender attached to http://jira.qos.ch/browse/LBCLASSIC-177 is currently doing. Here the preparation of the caller data is only be done if requested by the user via configuration.

I've implement asynchronous file appender, and enqueue events, but %caller pattern can not be used in the case of deferred processing becouse caller information is losed. My suggestion is to create Throwable object in prepareForDeferredProcessing

From http://blogs.sun.com/jrose/entry/longjumps_considered_inexpensive :

The most costly part of exception processing on the JVM is creating the exception, not throwing it. Exception creation involves a native method named Throwable.fillInStackTrace, which looks down the stack (before the actual throw) and puts a whole backtrace into the exception object. It's great for debugging, but a terrible waste if all you want to do is pop a frame or two.
