However, this has nothing to do with the OPs problems with FC3 using up memory and we could take this to another thread.


I couldn't agree more... I'll make another thread titled "Linux Sun's 
JVM needs improvement"

Unless I am retarded, which I might be, I think the the amount of memory
taken up by a VM is specified in the command used to start the java VM
something like -Xs512M -Xi512M come to mind, which would set the minimum
and maximum memory taken up at 512 Megs, so the amount of memory used by
the VM is configurable,  what is not however is how the garbage
collector utilizes that memory.  I cannot think of a single command on
any OS for any JM that would tell you how much of the heap was utilized.

Just my blathering


I don't have those two options in jdk.config. I do find the following
options in cbulder.config:

vmparam -Xms32m
vmparam -Xmx256m

So I wonder why the JVM instance invoked by CBX takes up more than
400mb memory?

To unsubscribe:
What command did you use to determine the memory size,  I know that a
simple ps -ef|grep -i java will tell you the exact java command that is
lauched with all of the options

I got the following two options after running ps -ef|grep -i java:

--Xms32m -Xmx256m

So that's exactly the same options in cbuilder.config.

BTW, I get memory footprint values from the System Monitor tool.
