In other words, we need to think about latency when our networks are under load, not when they’re idle.Īll that’s by way of introducing the networkQuality command-line tool that Apple introduced with macOS 12 Monterey. High-bandwidth activities can cause latency spikes that spell trouble for otherwise good connections for everyone on the network. Unfortunately, latency numbers reported by standard speed tests may not accurately reflect what you’ll see in the real world, such as when someone else on your network is enmeshed in a Zoom call, watching a 4K video stream, or backing up to an Internet backup service. Is a 100-millisecond latency good or bad? Low latency numbers are essential for smooth video calls and responsive gaming, though it’s difficult to connect a particular latency measurement with perceived performance. (Speedtest calls latency “ping.”) Latency measures how many milliseconds it takes for you to get a response from the remote server. Latency, which is often overlooked, can play a key role when bandwidth is otherwise sufficient for your purposes. All of those should provide roughly similar results for download and upload throughput, but those two numbers don’t tell the whole story. Ookla’s Speedtest may be the best known, and you can also turn to Google’s tool- search for “speedtest”-or Netflix’s Fast. There are numerous tools for testing Internet connection speeds. But how to quantify that? And if necessary, how can you fix it? If your video calls stutter or freeze, your Internet connection might be at fault. But because videoconferencing requires decent bandwidth in both directions, plus relatively low latency to keep the audio and video streams synced, it provides a clearer picture of your network quality. Even watching streaming video isn’t necessarily a good test, since it stresses only downstream bandwidth and streaming services use lots of tricks to avoid jitter and buffering. However, if you’re just loading Web pages or reading email, it’s unlikely you can get a sense of throughput. Videoconferencing has revealed to all of us how good-or poor-our Internet connections really are.
