Checking Latency with DreamBox

Geographical location, time of day, or user load may impact latency when using DreamBox.  To troubleshoot network issues or test latency, there are several options depending on the machine you are using.

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

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

Then press Command + V to paste the address above and hit Return to let it run.

FOR PC USERS

In order to test for latency on PC's, we'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.

Once Chrome is installed, 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 up with a number of options available. 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.
