Mark Struberg commented on MYFACES-3235:
----------------------------------------

+1. Logging cannot replace a debugging session. Please do not add too much 
debug info! Especially not in ELResolvers and stuff which gets called millions 
of itmes per second!
Most people seems not to be aware that even a logger.isDebugEnabled() is 
already pretty expensive compared to the tasks which get executed sometimes!

An example: we had such a logger in OWBs Interceptor stack and after kicking it 
out, our total performance was more then twice as good!

> Create infrastructure for improved logging
