Some high-speed particles lag/freeze the game

Creating a relatively small amount of particles at a high speed completely lags out the game (in 1.16 this doesn't happen).

How to reproduce:

RunĀ 

particle smoke ~ ~ ~ 0 0 0 100 20

Which only creates 20 particles, at the speed 100.

Observe the game freezing (only for a few seconds, a higher speed lags it out far more).

I went through every particle available to the particle command using the above method; I got:
