The water will not go faster than the stirrers RPM no matter how big the
spinner is.
You can slow the water velocity down using a high RPM stirrer and small
spinner, but everything [tallness, diameter] becomes interdependent and it
can get tricky...plus, there is a tendency to create a vortex funnel in the
center while velocity stays fairly low at the edges.

Ode, The size of the stirrer in comparison with the surface of the vessel,
influences the amount of mass stirred and the turnover. When defining
magnetic stirrer's speeds, one should also include the the size of the
stirrer. for instance a 1/2 " magnet creates little turnover at 100 rpm.
The same rpm with a 2" stirrer may spill the liquid.

Any speed that reduces sparklies and grey beard build up on the pressure
side of the water currents on round electrodes, or eddy side where
pressure turns a corner on flat ones.
10-40 RPM works well. 100 might.

What is a good RPM rate or range for a CS magnetic stirrer?
