dperf 是一个100Gbps的网络性能与压力测试软件。

优点

  • 性能强大:
    • 基于 DPDK,使用一台普通 x86 服务器就可以产生巨大的流量:千万级的 HTTP 每秒新建连接数,数百Gbps的带宽,几十亿的并发连接数
  • 统计信息详细:
    • 能够输出详细的统计信息,并且识别每一个丢包
  • 使用场景丰富:
    • 可用于对四层负载均衡等四层网关进行性能压力测试、长稳测试
    • 可用于对云上虚拟机的网络性能进行测试
    • 可用于对网卡性能、CPU的网络报文处理能力进行测试
    • 压测场景下,可作为高性能的HTTP Server或HTTP Client单独使用

Client Cores Server Cores HTTP CPS
1 1 2,101,044
2 2 4,000,423
4 4 7,010,743
6 6 10,027,172

注意:本测试基于单张25Gbps Mellanox CX4

测试环境配置(客户端、服务器)

dperf 的以上性能数据,基于下面的配置测试得到:

  • 内存: 512GB(大页 100GB)
  • 网卡: Mellanox MT27710 25Gbps * 2
  • 内核: 4.19.90

统计数据

dperf 每秒输出多种统计数据:

  • TPS, CPS, 各种维度的PPS
  • TCP/Socket/HTTP级别的错误数
  • 丢包数
  • 按照TCP Flag分类的报文重传数

开始使用

设置大页

#参考如下参数编辑 '/boot/grub2/grub.cfg',然后重启OS
linux16 /vmlinuz-... nopku transparent_hugepage=never default_hugepagesz=1G hugepagesz=1G hugepages=8

编译DPDK

#编辑'config/common_base'打开PMD开关
#Mellanox CX4/CX5 requires 'CONFIG_RTE_LIBRTE_MLX5_PMD=y'
#HNS3 requires 'CONFIG_RTE_LIBRTE_HNS3_PMD=y'
#VMXNET3 requires 'CONFIG_RTE_LIBRTE_VMXNET3_PMD=y'

TARGET=x86_64-native-linuxapp-gcc #or arm64-armv8a-linuxapp-gcc
cd /root/dpdk/dpdk-stable-19.11.10
make install T=$TARGET -j16

编译dperf

cd dperf
make -j8 RTE_SDK=/root/dpdk/dpdk-stable-19.11.10 RTE_TARGET=$TARGET

绑定网卡

#Mellanox网卡跳过此步
#假设PCI号是0000:1b:00.0

modprobe uio
modprobe uio_pci_generic
/root/dpdk/dpdk-stable-19.11.10/usertools/dpdk-devbind.py -b uio_pci_generic 0000:1b:00.0

启动dperf server

#dperf server监听6.6.241.27:80, 网关是6.6.241.1
./build/dperf -c test/http/server-cps.conf

从客户端发送请求

#客户端IP必须要在配置文件的'client'范围内
ping 6.6.241.27
curl http://6.6.241.27/

运行测试

下面的例子运行一个HTTP CPS压力测试。
#在server端运行dperf ./build/dperf -c test/http/server-cps.conf

#以另一台机器作为client端,运行dperf
./build/dperf -c test/http/client-cps.conf

文档

请访问https://dperf.org/.

限制

  • dperf 要求HTTP消息在一个数据包中,所以不适合7层负载均衡的测试。
  • dperf 要求独占使用网络接口。
  • dperf 没有路由功能。建议配合三层交换机搭建测试环境。
