"Re: Full Garbage Collection every few seconds – GC frees very little memory (JBoss 4.2.3 with JDK 1.5.0 64-bit)" To view the discussion, visit: http://community.jboss.org/message/572276#572276 -------------------------------------------------------------- Unfortunately the GC will be a never ending story. We have different settings for the same application in different scenarios or requirements. The adjustment is a balance between troughput <=> full stop time. For our application I observe that the OldGeneration is after a start phase, more or less, static. We adjust young generation experimental that only a small part will be alive if the area become full and no object will survive more than once. With this behaviour the GC is stable a good bandwidth, after a threshold the application become slower and because of this object alive more often. That you will see in the GC logfile and this indicate that the application is short before overloaded. -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/572276#572276] Start a new discussion in Performance Tuning at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&containerType=14&container=2078]
