8/15/2023 0 Comments Browser benchmark test![]() ![]() It includes top-level information as well as per-object statistics. The main type is results that are stored in a database to enable queries and visualisation in SamKnows One. There are three different types of test output from the SamKnows Website Performance Test. DNS resolution strategy (DNS, or DNS-over-HTTPS).Additional optional configuration parameters can be supplied for: This is very similar to how traffic congestion is monitored for the road network.Īs with the Web Browsing Lite test, the primary input parameter to the SamKnows Website Performance Test is the website to measure against. The test can potentially be run in any broadband router which is far more than what would be possible when testing with a selected few real user devices.īy periodically testing a large number of user networks the difference in performance can be seen over time. When scaling up the test to cover thousands of user networks a good overall picture of browsing experience over a large geographical area is achieved. The result is user specific test results. The loading operation involving the browser makes use of a server side data cache of HTTP data to be able to have full control of the timing playback. Instead a tunnel is established between the user's router and the offload server so that all traffic originates from the user's own network. Since web servers may produce content differently depending on the geographical location of the user the offload server never talks directly to any web server (e.g. The offload server makes sure that the web page with all its objects are loaded exactly according to the measured timings from the user's network. What is measured are DNS lookups and object transfers. The server runs the actual browser while the broadband router only performs time measurements between its network and the needed web servers. This device is not powerful enough to accurately portray the user equipment.īy introducing an offload server it becomes possible to test the browsing experience from the user's own network. However, what is available to us is the broadband router in each home or office. In an ideal world using real user equipment would give the most accurate measurements. Being able to identify where time is spent can be used to make better decisions when improving the network or increasing server performance. HTML, CSS or JavaScript) have other objects as dependencies which further increases the page load time if they are the bottleneck. Nowadays many websites require access to multiple web servers with different physical locations and there might be a bottleneck in just a small part of the network. This highlights what is loaded, why the page doesn't load fast enough or why a part of the page is broken. The measurement is the percentage of how much the page has been loaded visually.īesides knowing the time frame of the page load and its visual implications one can also look at object-specific details. The page starts all white and ends up in stages to the final picture. Page load progress can be defined by comparing the visual structure being loaded on screen against a reference screenshot of the fully rendered page. Since what is rendered on screen affects the user the most, a measurement of visual progress is needed. updating page statistics on a server) while others have less impact on the visuals. Some objects are invisible to the user (e.g. ![]() It does not necessarily mean that all objects that are included in the page have visual relevance. The goal of the test is to highlight how much waiting time is needed for a human to be able to start accessing the contents of the page. Since the browser is a graphical program that renders the page step by step as more objects are being received from the network the measurements must be made based on what is observable on the screen. The SamKnows Website Performance Test uses a full headless web browser to accurately capture the user experience of browsing a website from within a user’s network. ![]()
