It is not a good idea to multiplex Nixies. They

exactly when the voltage is applied. This means you can't go too
fast.
Mux'ed NIXIE calculators tend to have cycle times around the 400 to 1600 Hz
range, or, given 12-16 digits, an ON time in the order of 40 to 200 uS with a
duty cycle of 6 to 8%.
One calc I have has a cycle over 3KHz and ON time down around 16 uS.
Some characterisation of some nixie types, note the DRIVE column:
