Performance tests showed significant improvement in throughput:

Could you please switch to netif_get_num_default_rss_queues() ?
It used to return hard coded 8, but now it returns #physical cores / 2.
That's based on broad experience with Meta's workloads. Some workloads
need more some needs fewer, but broadly half of physical cores is
a good guess for 90%+
Assuming you have thread siblings in those vCPUs above it should
match what you want, too.
