When you ask someone how good their internet connection is, they almost always answer with a number - "It’s gigabit!" But there is more to the story.

For years, download speed has been the default metric for internet quality. Now that high-speed access is common across many parts of the world, speed is no longer the most important part of the experience.

What really matters for a good internet experience is Responsiveness, or how quickly your connection reacts when you actually try to do something.

While many tools have existed to measure aspects of Responsiveness, there has not been a commonly used metric that describes Responsiveness holistically.

At Orb, we defined (or more accurately redefined) the metric Lag to be that intuitive and easy to understand measurement of Responsiveness.

What is Lag?

Responsiveness has always been difficult to quantify. Technical metrics like latency, packet loss, and jitter exist, but each tells only part of the story. Understanding how these metrics combine to impact your experience is difficult at best, and at worst, it can even be misleading.

• Latency measures the round trip time of packets, but what if a few packets get lost along the way?
• Packet loss shows how reliably a connection avoids losing packets, but doesn't explain how those losses impacted your experience.
• Jitter shows variability in round trip times, but it's tricky to relate to real-world impact.

Understanding how these metrics interact (beyond just “they should all be low”) requires deep technical knowledge - far more than most people, even many engineers, care to learn.

For example, how much does a 1% packet loss rate impact your experience on a Zoom call? It's not an easy answer. If it's just an occasional packet and your latency is low, you might not notice it at all. But if multiple sequential packets are dropped or your latency is already high, it can cause video freezes, voice artifacts, and a frustrating experience.

You don't experience latency, jitter, or packet loss in isolation. You experience Lag.

Measuring Lag the Way You Experience It

We realized early on that in order to make Responsiveness truly understandable, we needed an intuitive metric that captured the combined effect of all the messy underlying details. It had to be expressed simply and meaningfully at the level where people actually experience it.

We created a Lag measurement approach that mimics real-world protocol behavior. Orb simulates the fundamental behaviors that protocols underpinning gaming, video conferencing, and web browsing share when responding to underlying network conditions, and measure performance at that level.

Orb measures Lag continuously, because Lag fluctuates moment to moment on most networks and you experience every second of it.

Orb captures a complete picture of your connection's Responsiveness over time:

• How quickly a voice packet would get through during a call
• How smoothly a game's movements would register
• How snappy clicking a link feels when browsing

Lag gives you a number that reflects how responsive your internet actually feels when you use it.

Looking Ahead

As we move into the next phase of internet evolution, where speed is abundant but responsiveness varies widely, we believe it's critical to give users a metric they can trust and understand.

Lag isn't just another technical number, it's the bridge between complex network realities and the real-world experience users care about.

At Orb, we're excited to help define this future, where internet quality isn't just about how fast your connection is, but how good it is.

Stay tuned, we’re just getting started. 🙂
