Re: [JBoss-user] jboss on linux (performance)
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. david jencks On 2003.03.19 13:03 David Luis Fernandes de Araujo wrote: > > > Hello, > > i'm running jboss on a linux machine (redhat 7.3) and each one of the > threads that jboss throws occupies 60 MB of memory. > Is this normal ? > What can i do minimize the memory usage ? > > Thanks > > .david > > > --- > This SF.net email is sponsored by: Does your code think in ink? > You could win a Tablet PC.

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.

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.

Re: [JBoss-user] jboss on linux (performance)
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. -danch David Luis Fernandes de Araujo wrote: Hello, i'm running jboss on a linux machine (redhat 7.3) and each one of the threads that jboss throws occupies 60 MB of memory.
