Hi Everyone, I've deployed a lab network in Azure and am experiencing some network throughput issues I didn't expect. Please consider the below network diagram.
In this case, the Resource Group RG-Router is a virtual appliance and the zero route to the internet. All servers run Windows 2019 Datacenter and only have private addresses assigned. az-svr2 communicates with az-svr3 via a "hub" vnet and related peerings. All resources reside in the US West Azure region and the VM sizes are below. For some reason, when transferring data to/from the two Azure US West hosted servers, I am only getting about 300Mbps throughput. All my resource says that these peered vnets should operate at Gbps speeds assuming the VM sizes support it.
Any idea why I might be seeing such poor performance?
