How to increase the network performance of the workloads running on the virtual machines ?

 Example :

you have 10 Standard_F2S_v2 Azure virtual machines.

Each virtual machine has two network adapters.

Preferred solution:

Enable Accelerated Networking

Accelerated networking enables single root I/O virtualization ( SR-IOV ) to a VM, greatly improving its networking performance. This high-performance path bypasses the host from the datapath, reducing latency, jitter and  CPU utilization, for use with the most demanding network workloads on supported VM types.
