<DIV><FONT face=Arial color=#000000 size=2>Hi All,</FONT></DIV>
<DIV><FONT face=Arial color=#000000 size=2></FONT> </DIV>
<DIV><FONT face=Arial color=#000000 size=2>I am trying to look whether there is any scope in improving tenuring distribution by changing survivor space or Max Tenuring Threshold. I have read some Tenuring distribution examples. But following tenuring distribution output of my application confuses me and not sure whether the young generation is well-tuned or not. The following tenuring distribution O/P is result of consecutive minor collections. It increases from age 1 to 3 (sometimes upto age 4) and then drops to age 1. It then again increases with each minor collection.</FONT></DIV>
