JVM Free Memory

[cytchiu]

I am running the loadtest to my JBoss cluster server say APP1 & APP2.
Althougt I have the same config to both servers, I found that the Memory usage for APP2 is much more in APP2 than APP1. Is this normal?

The same configurations to both servers are not always mean the same usage of memory in clusting.It also infected by the client requests each web server serves.

And in clusting,the requests each worker node serves are defined by the "lbfactor" directive,see below:

workers.properties

# Define Node1
worker.node1.port=8009
worker.node1.host=192.168.10.128
worker.node1.type=ajp13
worker.node1.lbfactor=1

# Define Node2
worker.node2.port=8009
worker.node2.host= 192.168.10.129
worker.node2.type=ajp13
worker.node2.lbfactor=3

As you can see as above,the node2(lbfactor=3) will serve three times requests more than the node1(lbfactor=1).In this situation,the memory usage of node2 maybe more than node1 depends your app.

Hope this will help you.
