Hello
we got some servers that we plan to use as CDNs that got NUMA CPUs. We plan to run only haproxy and varnish on those servers, sample lscpu -e below

I recently read Architectural limitation for nbproc? - #3 by willy and based on that, I did:
- disable irqbalance
- NIC interrupts on node 0
- pinning haproxy to node 0
What about varnish tho? Since it also heavily relies on network communication, it should be pinned to node 0 too, leaving node 1 completely unused? Or can I pin it to node 1 (or leave unpinned)?
This is not strictly haproxy related but I will be grateful for any kind of advice.
Thanks
Jakub
