When I look at the CPU usage I see that it never exceed 100%, except at the
startup, the CPU utilization may reach 170%.
I installed several scripts in order to record the load average of CPUs, memory
usage... but all the time, only one cpu is busy. What is the kind of tests
that I should
What tool? top?
The 170% should be a clue that JBoss AS is actually using more than one CPU.
Also, unless you place JBoss AS under heavy load you might not see CPU usage go
above 100%.
Both Gnome and KDE have tools you can use to monitor usage of individual CPUs.
If you use those, you
I have the same problem but I do not know what I should do. I use an
application that is running on a jboss 4.2.2 server. I noticed that jboss uses
only one processor all the time although I have a machine which contains 4
processors. I search on internet but I found no help.
my question is
Is there some OS config setting that is preventing JBoss AS from using all
procs? I have a quad-core desktop on on both Vista and Ubuntu I can get JBoss
AS to use all four cores.
Also, how are you determining that JBoss AS is using one one processor? The
startup tends to be single-threaded
No, there is nothing special you need to do to get JBossAS (or any Java app for
that matter) to use multiple processors.
What OS are you running? Is there any setting in the OS that might limit apps
to specific processors? I vaguely recall someone having this issue with Solaris.

It's a Linux box. I have to check with the network team to see what version of
the OS it's running though.

I have run JBossAS on multi-proc systems running Ubuntu, RedHat, and SUSE. I
have no problems keep multiple procs busy. What testing are you doing to gauge
processor usage? At work we run standard benchmarks, but I also run JMeter with
various web apps; usually 10 simulated users is enough to
