"Re: Performance issue related to logging in JBOSS 5" To view the discussion, visit: http://community.jboss.org/message/569801#569801 -------------------------------------------------------------- >From your description it's not clear if the performance issue is related >mostly to high CPU usage (because of writer threads) or because of high memory >pressure (which will trigger longer and frequent garbage collector pauses). For example, you might try adding to your File Appender configuration: <param name="ImmediateFlush" value="false" /> This will avoid flusing every log statement, thus reducing the stress on CPU, but will engage more memory. However the problem appears to me quite complex, so you will need a full CPU-Memory analisys. (By the way, I also am not aware of any issue related to log4j file Appender like the one you have mentioned). Hope it helps Francesco -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/569801#569801] Start a new discussion in Performance Tuning at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&containerType=14&container=2078]
