Can you tell us a little bit more about your machine?

Is it 16 logical cpus (hyperthread) or 16 cores ?

Are all the cpus on the same bus or is it a NUMA machine ?

That could explain the drop off.

That's probably it.

The machine is 32 dual-core CPUs, showing up as 64 CPUs and it is organized as 8
cells, each with 4 physical CPU chips.

How does the Xen hypervisor manage the inter-processor interrupts? I'm trying to
understand if there is something in the way the processors are managed that can
be changed to improve the way this scales on large multi-processor
configurations.

Best regards,
