Sylvain,
Although there is some overhead in the way log4j does its lookup, you should discover that the overhead is in the nano-second range.
Thus, for many applications the difference should be so small as to be unmeasurable. However, there are situations where the overhead makes a difference. In particular, when the logging is done at the "OS" or container level. We are aware of the problem. It will be addressed in future versions of log4j.
In any case, I would be quite interested in the numbers you come up with.
