4. Browser startup time
Browser startup time was measured by capturing the start timestamp in a
launching C program, passing it in the command line URL
argument to the page first opened, and then the
opened page computing the delta by recording the end
timestamp in the page's onload handler.
5. Page load time (perceived window open time)
Page load time was measured by taking the delta between load end and start time.
Load start time was the timestamp taken just before calling window.open(). Load end
time was the timestamp taken when the page onload handler was called. This
measurement was taken a 100 times and averaged for each condition on each platform.
The launching page sends the start timestamp to the
worker child that computes the delta and passes it on till
the number of windows meets the threshold as set in the original launching page.
