Re: [JBoss-user] jboss on linux (performance)

2003-03-21 Thread David Jencks
I think that memory usage is not reported accurately per thread and that
actually the total jboss memory usage is 60 MB shared among all threads.

 Hello, 
 
 i'm running jboss on a linux machine (redhat 7.3) and each one of the

 Is this normal ? 
 What can i do minimize the memory usage ? 
 
 Thanks

i believe this is all shared memory.  each thread reports the block of
memory, but it's all the same block.  in reality, it's probably only
using around 60M total.

2003-03-19 Thread Dan Christopherson
Are you looking at ps output? The memory is actually shared between all 
of the threads running in the same VM. It should be showing up under the 
'shared' column in ps or top output.

This deceptive reporting is an artifact of Linux's threading model: a 
thread is basically a process with copy-on-write of memory turned off.

Yes, behind a firewall.


You can also change the amount of memory that JVM has avaiable with -Xmx and -Xms flags. Run java -X for the non standard options.
