Is the focusing speed of Canon 85 12 really slow?

The focusing speed of Canon 85 12 II is really slow.

Focusing with 5Diii, 85 1.2 is very slow, and it can only be used for posing, so it is difficult to capture.

The voltages driven by 6D and 5Diii focus motors are the same. It is said that this lens will focus faster only when used on the fuselage of 1D series, because the focusing voltage of 1D series will be higher than that of 5D series and 6D series.
