Is it normal for the burst rate to slow down when you stop down the aperture?

Re: Is it normal for the burst rate to slow down when you stop down the aperture?

I turned off exp simulation, and it didn't fix it. However, I did discover something weird. So at max aperture (f/5.0 in my case), servo AF works as expected (7fps). Stopping down from 5.6-8.0 it slows way down (3-4fps), but from 9.0 and above, it quickens back up noticably (6 fps), although not to max speed. I'm so confused. I have every setting set to manual so I don't know what could possibly be changing.

Edit: after turning off my camera and on again, anything below max aperture resulted in the same, below max speed burst rate, but it was consistent at all apertures for some reason. I even turned off auto white balance but no change.

Also, if the exposure sim. and aperture thing were true, then the slowdown when using one-shot af shouldn't be happening.
