感谢@yanglimingcn，我们使用这个cr在高性能存储场景实现了run-to-completion模型（with spdk），对比事件模式在延时方面确实有了显著的改善。 测试环境：CentOS Stream 9，网卡Mellanox MT2892（200G*2）,磁盘dapustor H5100 业务场景：高性能存储 具体数据： 在128k写入，1w qps的情况下 【不使用 polling mode】 Avg-Latency: 115, 90th-Latency: 125, 99th-Latency: 131, 99.9th-Latency: 134 【使用 polling mode】 Avg-Latency: 82, 90th-Latency: 84, 99th-Latency: 87, 99.9th-Latency: 89 在4k写入，1w qps的情况下 【不使用 polling mode】 Avg-Latency: 55, 90th-Latency: 57, 99th-Latency: 60, 99.9th-Latency: 156 【使用 polling mode】 Avg-Latency: 36, 90th-Latency: 38, 99th-Latency: 40, 99.9th-Latency: 140, 可以看到polling-mode在高性能存储场景可以给业务带来20us+延时的收益 -- This is an automated message from the Apache Git Service.
