ok so basically nothing can be done except not calling Log4perl at all in the frequently executed code.

tested using a variable $self->{disable_logger} initialized once if the level is OFF and tested before calling log4perl (instead of $logger->is_debug()): my program takes about 25% less time, as expected... Log4perl is a bit disappointing, indeed.

Thank you for your answers!
