Kent, my SMP config is actually a kernel SMP config. I believe Russel has got the right point when saying that something is missing inside to admire the SMP at work. Actually again, the SMP behaves quite right, the system appears quite fine grained to allow most identical programs, when run in parallel, to run maxing all the available cpus all their way out. That even if the specific applications are not designed to accomodate their threads avoiding to step onto each other foot while executing. I'm satisified with FreeBSD smp as I can be with linux, apparently as far as I've seen till now. Yet, the problem is in xcpustate, and also possibly in xosview (not tried that yet). Thank you for all replies.
