This is certainly a pricey Procedure: 1.three - five situations slower for synchronous loggers. Synchronous loggers wait as extended as is possible right before they consider this stack snapshot. If no area is needed, the snapshot won't ever be taken. On the other hand, asynchronous loggers need to make this decision prior to passing the log concept to another thread; The placement info is going to be missing following that place.
