红帽全球峰会6.5. 调整 OVS 硬件卸载示例
要获得最佳性能，您必须完成其他配置步骤。
为每个网络接口调整频道数以提高性能
频道包含一个中断请求(IRQ)，以及触发 IRQ 的队列集合。当您将 mlx5_core 驱动程序设置为 switchdev 模式时，mlx5_core 驱动程序默认为一个组合频道，它可能无法提供最佳性能。
流程
在 PF 表示器上，输入以下命令来调整主机可用的 CPU 数量。使用您要提供的 CPU 数量替换 $(nproc)：
sudo ethtool -L enp3s0f0 combined $(nproc)
$ sudo ethtool -L enp3s0f0 combined $(nproc)Copy to Clipboard Copied! Toggle word wrap Toggle overflow
CPU 固定
为防止性能下降，请在同一 NUMA 节点中查找 NIC、应用程序、VF 客户机和 OVS。如需更多信息，请参阅配置实例创建指南中的在 Compute 节点上配置 CPU 固定。
