Geographical location, time of day, or user load may impact latency when using DreamBox programs. Depending on the machine you are using, you have several options to troubleshoot network issues or test latency. For the best experience, aim for a load time of under one second.
For Linux Users
If running a Linux machine, use the following curl command to check latency with DreamBox:
curl -o /dev/null -L -s -w %{time_total}\\n https://play.dreambox.com
For MAC Users
To test for latency on your Mac:
- Go to Applications - Utilities - Terminal
- Highlight the following command line and press Command + C on your keyboard to copy it:
curl -o /dev/null -L -s -w %{time_total}\\n https://play.dreambox.com- Press Command + V to paste the address above and hit Return to let it run.
For PC Users
To test for latency on PC's, you'll need to use the developer tools built within Google Chrome. If you do not have Chrome installed, it is available from Google's Chrome page.
To test for latency on a PC:
- Open a new window in Chrome and click on the three horizontal grey bars in the upper-right part of the window. Scroll down and select Developer tools.
- A new window will open showing a number of options. Select Network from the top of the window.
- Go back to the original Chrome window that was opened and paste the following URL in the address bar: https://play.dreambox.com
- Hit Enter and the developer tools window, previously blank, will populate with data showing a breakdown of time it took to access and load the page. In the bottom-right corner of the window, your total latency will be displayed:
If you would like to run the test again fresh, press ctrl + shift + R to do a hard reload of the website. We'd recommend running this a few times to create an average. It is also recommended that you run the latency test multiple times throughout the day, especially during the times you expect students to be using DreamBox from your location.
