A method for communications includes receiving in a network interface controller (NIC) of a host computer incoming data packets from a network on multiple active rings. An average throughput rate of the incoming data packets is measured over the active rings. For each ring among a plurality of the active rings, a respective throughput rate of the incoming data packets on the ring is measured, and a respective interrupt moderation parameter of the ring is set responsively to a comparison of the respective throughput rate on the ring to the average throughput rate. Interrupts are issued from the NIC to a central processing unit (CPU) of the host computer in response to the incoming data packets on the ring at a rate determined in accordance with the respective interrupt moderation parameter.
