Explanation

For virtual desktop workloads, every keystroke, mouse movement, and screen update must travel between the end user and the cloud data center in real time. Network latency (C) - the round-trip time for packets - is the single most critical factor affecting user experience. Even a few extra milliseconds of latency makes desktops feel sluggish and unresponsive. While physical distance (A) correlates with latency, it is not the same thing - routing paths, peering agreements, and congestion can make a geographically closer data center have higher latency than a farther one. The combined distance metric (B) is not a real performance metric. Being in the same state or country (D) is too coarse a measurement and does not guarantee low latency.
