Traffic latency between VNETs

Hello, what could be the reasons for the traffic latency from VNET1 to VNET2?

The networks are located in the same region, and there is a connection between them.

However, VNET2 uses a subnet with public addresses like 20.58.x.x (so that they are the same as in prod). The VNET1 network uses private addresses from network 10.

I'm using Network Watcher - Next hop and making sure Next hop type is VirtualNetworkPeering.

It may be possible to find the reason without connecting to the host (unfortunately there is no access).

I saw an article that could help investigate, but unfortunately I do not have access to the VM.

Thank you!

    That's an anomaly. Verify that the latency is not tied to the VMs.
