Slow connectivity between Azure and On-prem (on-prem to Azure seems to be OK)

Hi Guys,

I have an application with MySQL and web services on Linux VMs.

I'm doing some tests with MS Azure, and when I have all the Back-ends and Front-ends on Azure, my performance is very good afterall. However, when I split my VMs (no excuses, I need to have the design like this), on an hybrid cenario with my back-end on-prem and my front-end on Azure, the connectivity is ultra-slow (with VPN, using RRAS).

RAW transfer data it's quite good (>50 MB\s), however, when I do some request's on my back-end, an query estimated to have 30 seconds of duration can easily take more than 2(!!!) minutes.When traffic is sent from my datacenter, I monitored, and the performance is very good. Then traffics is sent from Azure, the results are really bad.

Any suggestion?

Best regards,
