数人云测试报告

通过阅读本章您可以对数人云的性能有一个大致了解

测试报告

高并发，大 qps 测试

首先，数人云网络架构需要硬负载（譬如F5）与软负载（Haproxy）结合使用。 数人会根据流量预估来提前铺设（可自动或手动）多个HAproxy实例及相应的业务层实例。

接下来，当请求到达时，硬负载首先将请求均衡到后面的某个HAproxy上，然后，HAproxy再把相应的请求负载均衡转到它后面的业务层实例上。这其中的Haproxy 与 业务层实例都可以横向扩展。

下面是不考虑硬负载性能的情况下， 对数人云(Mesos)及 Haproxy 的测试结果：

Mesos 集群性能测试

铺设的实验环境，Mesos 集群在

  • 3 个 master 节点
  • 500 台虚拟机
  • ubuntu 14.04 x86 * 2核4G

前提下， 经测试可以承载10000个 docker 容器（nginx）。

数人云网关节点（HAproxy）的性能测试

  • 官网发布的物理机上的测试结果

    10G的网络，8KB的测试包，HAproxy 单进程每秒能处理 2万5千个请求

  • ucloud 云主机上的测试结果

    • 承载云主机的物理机：未知
    • 网卡：未知
    • 虚拟机
      • 2vcpu
      • 4G mem

    • 测试架构：

      apache benchmark -> HAproxy -> 3 个 Nginx实例

      测试1

      传输 128字节，使用apache benchmark 进行测试， HAProxy 负载均衡到后面3个实例，它大约能承载每秒 2000 个并发， 11000个请求。另外，cpu使用率高于 90%, 内存使用率低于 300M。
