Log4D is a port of the well known log4j logging framework to Delphi. As the original project (https://log4d.svn.sourceforge.net/svnroot/log4d/trunk) seems not to be maintained actively, I decided to fork a branch with valuable improvements.
It supports now an advanced feature called 'parameterized logging', which can significantly boost logging performance for disabled logging statement. If the current log level is lower than the global log level, log message will not be concatenated.
- Using original Log4D:
LOG.Debug(Format('Invalid value %s' [Value]));
- Now:
LOG.Debug('Invalid value %s', [Value]);
