That's not true. NIC queues and CPUs are still very important to get good performance on servers by pinning different queues to different cores.

  Only if your workload involves passing around a lot of network traffic (e.g. a load balancer) or is highly latency-sensitive. I've got backend servers that routinely max out 32c/64t CPUs but push so little traffic that replacing the NIC with a cell phone modem would make no discernible difference. There are many types of server workloads where the NIC is not the bottleneck at all, so the parent's argument that low NIC queue counts make high CPU core counts useless is false.

    The parent said "but it might not be useful". "Might" being an important word here.

    "Server use cases can often run more threads, but it might not be useful" != "low NIC queue counts make high CPU core counts useless " You're debating an argument that was never made.
