Performance Improvement #17

Closed ferronrsmith closed 9 years ago

ferronrsmith commented 10 years ago

Performance To improve the performance of the debug, it is a good idea to surround your logging statements with appropriate isXXXEnabled() methods to evaluate before logging if the required logging level is enabled:

  if( myLogger.isDebugEnabled()) {
    myLogger.debug(...);
  }

If debug is disabled, it is much faster to evaluate only if it is disabled than constructing a possible complex message before finding debug level disabled. But this makes only sense when the messages are a little bit more complex than just log a simple string. Otherwise the sources are blown up too much with condition statements which is not much readable.

Should be added to the documentation for users to know.
