Interrupt Optimization

  1. When the CPU usage of the openGauss database is greater than 90%, the CPU becomes a bottleneck. In this case, you need to enable offloading to offload network slices to the NIC.

    Run the following commands to enable the tso, lro, gro and gso features.

    ethtool –K enp3s0 tso on 
    ethtool –K enp3s0 lro on 
    ethtool –K enp3s0 gro on 
    ethtool –K enp3s0 gso on
  2. Run the following command to bind the NIC interrupt queues to the CPU core.

    sh  16
