1) Unravel the acronyms. I'm pretty sure VMSS and Flexible server are
referring to Azure services, but it would be better if that was
explicitly stated.
2) Show your work. In other words include the query plan, database
script and the dynatrace results in your response.
3) What is "If i run single sql transaction from pg admin
it is executing in same time." trying to say? The same query as you
refer to earlier and how does a single query relate to the issue of
running transactions in batches?
My guess is that the Flexible Server(PaaS) is imposing more of an
overhead then running your own Postgres instance on IaaS(Azure?).
