![]() Ookla uses three main measures of latency, each of which helps you understand a specific set of issues. Whether AR and VR or self-driving vehicles, this will require dramatic improvements in latency. ![]() The future of the internet is bidirectional where download and upload communication are necessarily performed simultaneously. Latency will matter even more in the very near future Using regression, we show that an additional increase of the startup delay by 1 second increases the abandonment rate by 5.8%.” Of course, network operators don’t control the full experience here, and things like CDN location can really affect an end user’s experience, but consumers don’t have visibility into that and the more you can optimize the portions you do control, the less negative feedback you’ll receive. In fact, one study from the University of Massachusetts Amherst and Akamai concluded “…an increase in the startup delay beyond 2 seconds causes viewers to abandon the video. Think back to the Amazon example above: You may not be directly losing money when your customers see a slow page load due to high latency, but you are providing a poor network experience that will result in increased customer service costs and churn. Above the 300 ms barrier, it’s difficult to maintain a coherent conversation. This is a physiological threshold - below 300 ms - where the human brain can manage the delay and not speak over other parties. In addition to web browsing, video and voice calling needs a latency below 300 ms to provide an acceptable experience. It can take 7x to load a full webpage when latency is high, as seen in the example below. On a gigabit connection, 500 ms of additional latency dramatically affects the page load time. As a result, the typical request on the internet requires two to five round trip communications between various entities over different latency sensitive protocols (DNS, TCP, TLS, and QUIC/H3). While best known for gaming, video conferencing, and streaming video, the underlying internet protocols powering modern experiences rely on bidirectional communication to negotiate encryption keys, determine routing paths, and request resources. Latency matters for every online experience. Latency is the bidirectional roundtrip time between two endpoints. While speed has always been the focus for optimization, since the end user delay was caused by the delay of downloading data assets, now that bandwidth has increased for many people around the globe, the bottleneck for these folks is the time delay between two systems communicating. Why latency mattersĪ 2009 study detailed that every 100 ms of additional latency on, cost the company 1% of revenue. Read on to learn why latency matters to quality of experience, why you need to consider latency now, and how Ookla® can help you measure what matters most.īandwidth is now an economics problem, latency is the new opportunity horizon. ![]() While latency has always affected connectivity, latency and responsiveness metrics have become increasingly critical to network operators focused on delivering a superior connected experience and supporting evolving consumer use cases. However, the internet and how we use it is changing bandwidth is no longer all that matters for networks operators to deliver on the possibilities that a connected world can offer. Internet service providers and mobile operators have spent decades optimizing their networks to provide the best speeds possible so consumers can achieve seamless connected experiences.
