comment High-availability for ZMQ traffic
I'm wondering, will HAProxy in tcp mode work? Probably not, due to multi-part ZMQ messages (which ought all go to the same machine)... Is there a way to teach HAProxy that?

comment A roundrobin for incoming files
@sysadmin1138 Is that a good thing? Will Google find chat logs? Will they be readable enough to be a viable self-education material for other people?.. (That's off-topic, of course, so I'm shutting up. Thanks.)

I would very much appreciate if people who voted to close this question, elaborated on their motivation in the comments. Especially the off-topic vote. Thank you.

comment How to change SMP affinity of an IRQ on Ubuntu PV domU inside Xen XCP?
thank you, I'll look into that. But I'd like to see an authoritative answer on why affinity configuration does not work. It worries me that everyone seems to assume that it is possible, but I can't do that.

Thanks, but, would it help or not is outside of the scope of this question. Your help is very welcome here: serverfault.com/questions/446173/… or here: serverfault.com/questions/446081/uneven-cpu-core-utilization

Note that irqbalance is running. Maybe I'm just doing it wrong?

comment CPU0 is swamped with eth1 interrupts
I've got an impression that smp_affinity_list is not supported in 2.6. Also, I did try that in hex, actually... Anyway, moving this to a question I linked to — will try tomorrow.

Erm. No, still can't change that. Can't figure out what is going on. Will ask a separate question for that.

Nevermind that — I tried it on wrong machine with 4 cores instead of 8.

BTW, I see /proc/irq/283/affinity_hint, but can't find proper docs for it. Can't this be related?

echo $((2**8-1)) | sudo tee /proc/irq/283/smp_affinity gives me Input/output error (irqbalance is stopped).
