Quality of Experience tests
Good internet performance is particularly important for gaming. Beyond downloading your 100GB game, gamers need fast latency and low packet loss to stay competitive when gaming online. Gaming servers are spread out all over the world, but the physical distance and performance to each of them is unique to every gamer.
We’ve built tests for the following popular games, to test the round-trip latency and packet loss performance to their real-world gaming servers. More games will be added over time.
League of Legends
The IP address of the node that the user was directed to.
The average, minimum and maximum round-trip times of the ten packets.
The number of packets sent and received, allowing packet loss to be calculated.
Our video conferencing tests measure round-trip latency and packet loss to the most popular online video conferencing services.
Many different protocols and communications are used during video conferencing. Our measurement focuses on traffic to the video and audio relay servers, as problems on this link will differently manifest as connectivity and quality issues to end users.
Average round trip latency for 10 UDP packets (by default).
Minimum, maximum, meditation and standard deviations for the latency measurements.
The number of sent and received packets.
The IP address of the endpoint.
We have developed a variety of video streaming measurements that stream real content from major video streaming providers. This allows you to gain an accurate view of how video is delivered to customers.
The bitrate reliably streamed
The startup delay (the time taken to download two seconds of video)
The TCP connection time
The number of stalls and their duration (this is only applicable if the test is not running in the ‘bitrate reliably streamed’ mode)
The downstream throughput achieved
CDNs are widely used by large websites to distribute static content near to end users. This reduces the burden on the content providers' servers and improves web page load times. CDN operators will place caches inside ISP networks so that traffic does not even need to leave the ISP network. This is beneficial for both the ISPs (it reduces the load on their transit and peering links) and the CDN operators too (it spreads the content serving burden to a wider array of servers).
TCP connection time
Object fetch time (lower is better)
The IP address of the CDN node
Load real pages from real websites to assess browsing performance that users would actually see in their homes rather than to a centralised test server.
Website Performance Test
This test uses a full headless web browser to accurately capture the user experience of browsing a website from within a user’s network. The measurements are based on what is observable on the screen, the goal is to highlight how much waiting time is needed for a user to be able to start accessing content on the page.
Web browsing lite
Measures the time taken to fetch the HTML and referenced resources from a page of a popular website. This test does not test against centralised testing nodes; instead it tests against real websites, allowing for content distribution networks and other performance enhancing factors to be considered.
