Hi I have had no luck with responses on the user list so I would like to pose my question to the Log4j dev group. I'm basically wondering if log4j has the ability to queue log requests. I noticed JLog's Handlers (roughly equivalent to log4j's Appenders), in their default, asynchronous mode pull log records off a queue and process them "at their leisure." While I know Log4j features asynchronous logging, does that necessarily imply that a queue is used? Can someone please clarify? Thanks, Craig Reichenbach Original Message: In looking at Log4j source, if one uses a File based Appender, it looks like calls to the various Category log functions (debug, info, error, etc) are held up until the actual File I/O occurs via the QuietWriter class. I did notice the immediateFlush boolean in WriterAppender, and although it helps performance, it is considered a heavy tradeoff to turn off immediateFlush. I just want to make sure that I am not missing anything; Log4j does not have message queing functionality does it?
