Felven2026-02-26 8:11

1、硬件环境

鲲鹏服务器，两个920s，共64核 主频2.6G，内存256GB 主频2933MHz，N20网卡 PCIE速率 4.0x8

bash 复制代码 
[root@localhost /opt#] lspci -s 01:00.0 -vvv | grep LnkSta
LnkSta: Speed 16GT/s, Width x8 (downgraded)
LnkSta2: Current De-emphasis Level: -6dB, EqualizationComplete+ EqualizationPhase1+
[root@localhost /opt#] lspci -s 01:00.1 -vvv | grep LnkSta
LnkSta: Speed 16GT/s, Width x8 (downgraded)
LnkSta2: Current De-emphasis Level: -6dB, EqualizationComplete- EqualizationPhase1-

2、软件配置

操作系统：麒麟信安3.5.2 内核版本5.10.0

/etc/sysctl.conf 文件配置缓存区

bash 复制代码 
net.core.rmem_max=67108864
net.core.rmem_default=67108864
net.ipv4.udp_rmem_min=67108864
net.ipv4.tcp_mem=218910000000 291910000000 437820000000
net.ipv4.tcp_rmem=67108864
net.ipv4.tcp_wmem=67108864
net.core.netdev_max_backlog=3000

关闭中断负载均衡，网卡中断设置亲核性

bash 复制代码 
systemctl disable irqbalance
systemctl stop irqbalance
sh set_irq_affinity 0-31 enp1s0f0

3、陪测设备

鲲鹏计算模块，鲲鹏920s，32核 2.6G，内存64GB 主频2933MHz 鲲鹏100G自带网卡

4、iperf测试

5、结论

N20作为client端，发送速率最大就84GB/s左右，无法提升

N20作为server端，接收数据，如果要稳定在90GB/s以上至少需要6个核，5个核的时候运行一段时间CPU占用率会跑到100%，导致后面速率下降。
