Here is the GC data charps record by Jconsole come with JDK1.5. One houre later, major GC become so busy...and the Throughput in Jmeter become decrease with the time. I have increase the heap size above to 1300M. If more rhan 1300M, there will throw error ...So maybe in my enviroment the heap size limited to about 1.3G.
Should i increase the survior space?
Or there's something else going unnormal in my enviroment?
It looks like one hour later, one minor GC can only collect little die objects in survivor space, there are many objects are survivoring.
Then in the next minor GC time, lived objects fills up in the survivor space, any remaing live objects will copy to tenured generarion.
So we can see, major GC become more and more often then that in the first hour...
But what make me adoubt as why one hour later, the objects become difficult to release...
Can somebody help me to find out the problem with me?
