CPS多核模式下报错-怀疑是RSS算法导致的，有没有什么调优的方法呢？

作者你好，我使用单核测试的时候可以达到320K的CPS，但是使用多核的时候报错就很严重，基本不能正常工作，还不如单核的性能：

client用的是dperf吗，试试rss auto

[yingweizhao]

client用的也是dperf-同一台机器，我的内存插槽没有满配，服务器是两个海光CPU，64核心128现场，rss auto基本只能跑在1个Core上面， 巨页内存： [root@localhost ~]# cat /proc/meminfo |grep -i huge AnonHugePages: 8192 kB HugePages_Total: 64 HugePages_Free: 52 HugePages_Rsvd: 0 HugePages_Surp: 0 Hugepagesize: 1048576 kB CPU架构： [root@localhost ~]# lscpu Architecture: x86_64 CPU op-mode(s): 32-bit, 64-bit Byte Order: Little Endian CPU(s): 128 On-line CPU(s) list: 0-127 Thread(s) per core: 1 Core(s) per socket: 1 Socket(s): 128 NUMA node(s): 8 Vendor ID: HygonGenuine CPU family: 24 Model: 2 Model name: Hygon C86 7380 32-core Processor Stepping: 2 CPU MHz: 1200.000 CPU max MHz: 2200.0000 CPU min MHz: 1200.0000 BogoMIPS: 2399.88 Virtualization: AMD-V NUMA node0 CPU(s): 0-7,64-71 NUMA node1 CPU(s): 8-15,72-79 NUMA node2 CPU(s): 16-23,80-87 NUMA node3 CPU(s): 24-31,88-95 NUMA node4 CPU(s): 32-39,96-103 NUMA node5 CPU(s): 40-47,104-111 NUMA node6 CPU(s): 48-55,112-119 NUMA node7 CPU(s): 56-63,120-127

打吞吐使用RSS算法就工作正常，打CPS就不正常

[yingweizhao]

使用的是intel XL710 40g网卡

server ip数与cpu数目一致，不要配置rss。 如果喜欢dperf，请加个star，谢谢

[yingweizhao]

好的，谢谢，我试试，加star-没问题，deperf确实非常不错
