Does disabling unused entities speed up Home Assistant?
Devices often have entities that I would never use.

Yes, but most of the speed ups will be small and unnoticeable.
Your history/recorder will benefit greatly from it though, if these are not already excluded.

how do you exclude them from the recorder?

4

Excluding or including. Here is explained with examples.

I prefer to exclude everything and then only include whatever I want.

recorder:
  purge_keep_days: 14
  include:
    entities:
      - sensor.xiaomi_mi_scale_peso # por esphome
      - sensor.peso_arturo # por esphome
      - sensor.peso_yessi # por esphome
      - sensor.xiaomi_mi_scale_impedancia # por esphome
      - sensor.mi_body_composition_scale_4ed2_mass
