Websphere CPU usage

I am experiencing the following phenomenon in WebSphere: I have a multi threaded process on a multicore machine, but when I see the CPU consumption it appears two CPUs are in use of 100%. The two others are not in use at all.

How is this determined? Can it be tuned by WebSphere? Is it something 开发者_StackOverflow中文版in my AIX os?

Thank you!
