(See the comments of LOG4J-151 for a discussion of latency versus > application throughput and logging throughput.) > I believe it is possible to improve this performance by an order of magnitude > by having an asynchronous Logger implementation that hands off the work to a > separate thread as early as possible. The disk I/O would be done in this > separate thread. > AsynchAppender is not a good match for these requirements, as with that > approach (a) the logging call still needs to flow down the hierarchy to the > appender, doing synchronization and creating objects at various points on the > way, and (b) when serializing the LogEvent, the getSource() method is always > called, which is expensive. -- This message is automatically generated by JIRA.
