Some freezers have a "fast freeze" switch which lowers the temperature
of a part of the cabinet specifically so you can freeze things better.
If not, adjusting the dial so that the compressor is on continuously for
a while has a similar effect. Don't forget to put it back to the normal
position once everything's frozen though!

The "Fast Freeze" switch on freezers just shorts out the thermostat and makes
the compressor run continuously.

Exactly, which means the temperature ramps down faster after opening the
door and placing something warm inside.


How does running the compressor make things get colder faster as opposed
to running the compressor?


because the tstat is usually limited to around -40 C. The compressor and
gas charge will usually evaporate even lower, so you can have more
cooling "left over". If you switch to "super" before loading it, the
thing starts at -50 ish and cools commensurately faster.
