ISTR it being something on the order of running 32 instances of top(1),
one per cpu, and then trying to fork().
I think this is one of those that needs num_cpus_online() >= 32, and
possibly in combination with strong NUMA effects. I'm willing to accept
large delays with respect to addressing this unless my employer/funding
source makes equipment more readily available.
Seriously -- if those who could need and/or fund the fix don't see it
as a large enough problem to invest in a fix for, I see no need to
impose on the Linux kernel community to do so.
Otherwise, given sufficient hardware access, I'd be more than willing
to run regular tests on whatever patches you care to send me. As of now
I'm not even able to do so, regardless of willingness.
(e.g. access to 64GB hw, even while in-house, has been extremely limited)
