《Windows Azure Platform 系列文章目录》
- 不要使用使用Ping命令测试Azure可用区之间的延迟，ping使用icmp，优先级低导致测试数据不准确，并也不支持Azure虚拟机的加速网卡
- 使用4Core或以上核心的CPU
- 测试环境是West US 3的3台虚拟机
| 虚拟机名称 | 内网IP |
| zone1-vm | 10.0.0.4 |
| zone2-vm | 10.0.0.5 |
| zone3-vm | 10.0.0.6 |
测试工具是使用socketperf，具体部署文档：https://learn.microsoft.com/zh-cn/azure/virtual-network/virtual-network-test-latency?tabs=linux#test-vms-with-latte-or-sockperf
测试结果
| Zone1 | Zone2 | Zone3 | |
| Zone1 | 329 us |
597 us
|
|
| Zone2 | 329 us | 499 us | |
| Zone3 |
597 us
|
499 us |
测试结果：
我的逻辑zone 2 -> zone 1的RTT来回时间，平均是329微秒
