Does disabling Interrupt Moderation increase CPU usage?

On modern multi-core gaming CPUs, the extra CPU usage is less than 0.5%, but the packet latency reduction is immediate.

Interrupt Moderation Delay & Energy Efficient Ethernet Packet Queuing

Factory network adapter settings enable "Interrupt Moderation" to batch packets together to save tiny amounts of CPU usage, adding 2-5ms of artificial delay to every gaming packet.

For competitive gaming, incoming packets should be handled immediately. Interrupt Moderation and Energy Efficient Ethernet (EEE) delay packet processing. We disable Interrupt Moderation, configure Receive Side Scaling (RSS) to spread packet processing across fast CPU threads, disable EEE green ethernet states, and optimize UDP receive buffers.
