Reading out the end time in browser speed tests
A few weeks back I did some DOM speed tests on mobile browsers (results forthcoming). The most important result of these tests is not the actual values (although they’re interesting), but the fact that I could finally prove a theory that I’ve had in the back of my mind for at least two years now.
Basically, when setting up a speed test you should be very careful to allow the browser to render the result on screen before you close the test by reading out the second timestamp.
