Again, all I can tell you is that all your performance penalty is in the following line:

if (logger->isEnabledFor(level))

If you are not willing to pay it at production runtime, you have a choices of wrapping your calls into #ifdefs or redefining LOG_DEBUG into nothing and have compile time control.

I am not aware of built-in compile time control mechanism with log4cxx.
