问题描述
我有一个案例，我使用Azure网络作为两个客户办公室之间的传输，因此为什么我使用站点到站点VPN而不是全局对等.
I have a case where I am using the Azure network as a transit between two customer offices, hence why I am using site-to-site VPN instead of global peering.
在Azure西欧和Azure West印度之间配置VPN时，有时会有相当长的延迟(大约280毫秒)，有时会下降到140毫秒.当仅测量区域之间的延迟，但要测量公共IP时(所以我不使用 隧道)，延迟始终在130-140毫秒左右.
When configuring a VPN between Azure West Europe and Azure West India, I have a quite high latency sometimes (around 280 ms) and sometimes it drops down to 140. When just measuring latency between regions, but to the public IP (so I am not using the tunnel), the latency is always around 130-140 ms.
VPN开销增加一点就可以了，但是两倍似乎没有关系.区域之间的VPN流量处理方式不同吗?
That the VPN overhead add a bit is OK, but double does not seem related. Is the VPN traffic between regions handled differently?
作为参考，我在西欧和东亚之间有类似的设置，并且没有遇到相同的问题.
For reference, I have similiar setup between west europe and east asia, and do not experience same issues.
非常感谢！

Hello Jimmy11122，
这可能是影响延迟时间的广泛问题站点到站点VPN网关连接.
例如，不同的Internet提供商，您的VPN网关已到达100％的利用率，使用旧型号，您的VM获得100％的CPU使用率，等等.
最常见的问题与设备兼容性有关.只要您的设备符合所有IP安全要求，它们仍可以正常工作，但是 不兼容并导致性能问题:
The most common issues are related to device compatibility. Your devices may still work as long as they meet all the IP security requirements but it may not be compatible and cause performance issues: https://docs.microsoft.com/en-us/azure/vpn-gateway/vpn-gateway-about-vpn-devices#devicetable
