Here's a pretty good pdf with explanation of different spike suppresion
methods.
It lists drop out times for the different methods, for one particular relay
and values.

PS. A diode is the slowest dropout time listed.

Note also that the diode is also the best at suppressing the spike.

Note also that UNsupressed is the only way to get it fast. ALL the
other methods slow it.

Note that you contradicted yourself.

Note also that you are an ignorant berk.

Note also that you have no clue as to how inductive circuits behave.

ALL of the other methods violate his 'issues' list.

In many cases, that is the most important constraint (the spike).
Note also that all the figures are for 12V relays, which are not in much
use on modern low voltage circuit designs these days.

I am quite certain that any 3.3V relay you choose to examine will prove
to be faster than any of the numbers that more than 10 year old document
measured. Even the diode.
