What should be configured to provide hardware-accelerated inter-VDOM traffic?

Comprehensive and Detailed Explanation From Exact Extract documents and Knowledge:

Standard communication between two Virtual Domains (VDOMs) on the same FortiGate is typically handled by a " VDOM link, " which is a virtual interface pair processed by the CPU. However, for high-bandwidth environments where low latency is critical, Fortinet provides NPU vlinks (Network Processing Unit virtual links).

NPU vlinks are a specific type of hardware-accelerated virtual interface that resides directly on the Network Processor (NP6, NP7, etc.). By using NPU vlinks instead of standard software-based VDOM links, traffic between VDOMs can be offloaded to the NPU hardware, which provides significantly higher throughput and near-zero latency by bypassing the FortiGate ' s main CPU entirely. This is the standard recommendation for accelerating " East-West " traffic in a segmented data center or campus environment.
