80D focus speed slow in live view?

Hi,

I was doing some experimentation, trying my 80D with a 100-400mm ii lens today, using Live View, and I was kind of surprised that the auto-focus was taking forever (like seconds) to focus.

I was surprised because I had seen videos like this one:

which seemed to indicate that the AF in Live view was fast?

Now, when I did this, I have my 80D in AI Servo, single point (I had tried the multipoint earlier and it was ever slower), continuous, and this was in bright sunny day.

So I was wondering:  Was my AF slow because I had it in AI Servo, i.e., is the AF only fast in single focus?

Or, should I be able to get the AF working faster even with AI Servo, and if so, how?

Thanks,

Jim
