I wonder if all of the threads in a process might be pointing to the same struct rusage? Nope, checking kern/kern_resource.c kern_getrusage(), there is a per-proc struct rusage_ext which gets the sum of the per-thread td->td_ru counters via rufetch() / ruxagg()...so you're right that the counters are now per-thread. > Which would mean that a process that is occupying memory but doesn't happen > to be running on that clock tick doesn't have its memory counted toward the > total ... right? That's right.
