Configuring the NIC Interrupt Coalescence

Purpose

If the interrupt coalescence adaptation is enabled, interrupts are automatically coalesced when small packets account for a large proportion on the network, improving system performance. In the current test model, small packets account for a large proportion. Therefore, interrupt coalescence needs to be enabled.

Procedure

Enable interrupt coalescence, assuming that the current NIC name is enp136s0.

ethtool -C enp136s0 adaptive-rx on
