-Network Optimized Virtual Machines in Azure introduce advanced performance enhancements to networking, including accelerated connection setup, increased network bandwidth per vCPU, and support for more virtual network interfaces per vCPU. These improvements significantly reduce connection setup latency and enable higher connection creation rates, making them ideal for demanding workloads.

-Network Optimized Virtual Machines is built on the foundation of [Accelerated Networking](../../virtual-network/accelerated-networking-overview?tabs=redhat). Network Optimized Virtual Machines offload initial connection setup to hardware using [SR-IOV](../../windows-hardware/drivers/network/overview-of-single-root-i-o-virtualization--sr-iov-). This enhancement reduces connection setup latency and enables virtual machines to manage more connections efficiently within application constraints.

 Network Optimized Virtual Machines feature updated network flow limits that scale with vCPU count, offering greater capacity compared to general-purpose Azure virtual machines. These capabilities make Network Optimized Virtual Machines a powerful choice for applications requiring high-performance networking and scalability.

 ## Network connection limits for network optimized virtual machines
 
-Connection and flow limits for Network Optimized Virtual Machines are adjusted to enhance scalability and ensure consistent performance. These limits depend on the vCPU count of the virtual machine. When the connection or flow limit is reached, any new packets attempting to create connections or flows beyond the limit are dropped.

 Network Optimized Virtual Machines reduce latency for connection creation and enable higher connection creation rates. The connection creation rate, also known as connections per second (CPS), depends on several factors. These factors include virtual machine performance, operating system configuration, application settings, network traffic type and behavior, and infrastructure load. By optimizing these elements, you can achieve improved CPS performance in supported scenarios.
 
-CPS throttling occurs for network optimized virtual machines based on the number of vCPUs in the virtual machine. If the workload creates connections at a rate exceeding the infrastructure limit, the system drops packets. Once the connection creation rate falls below the limit, the system allows more connections to succeed. When testing CPS, consider that virtual machine connection limits and flow expiration directly affect the sustained testing of the maximum connection creation rate.
