Very relevant. A lot of websites need 5 to 30 seconds or more to load.

I have a suspicion that the 30 second loading time is not caused by TCP slow start.

Slow start is about saving small-integer-numbers of RTT times that the algorithm takes to ramp up to line speed. A 5-30 second load time is an order of magnitude off, and almost certainly due to simple asset size.
