Log for the bare necessities, the simple bare necessities

Why did you do that if you weren’t asked to? Improving performance means doing just the minimum tasks. As stated in “Performance” section, http://logging.apache.org/log4j/1.2/manual.html , we’d better check if we need creating tonns of strings in java. So

if (log.isDebugEnabled()) {

log.debug(“Create” + “this” + message + “string”);


prevents creating unneeded debug/trace strings.
