Excessively Long Load Times for Form

When going into edit mode of a profile account, it takes an excessively long time to load the form.

The form has over 150 fields.

1 – is there a way to speed this up?
2 – is there a way to break up the form into several forms and still populate the profile correctly?

This video shows it takes over a minute to load: https://gyazo.com/e7a7c3da5aa2c7d61c499ae50cc876a8

It actually took a minute-thirty to load but gyazo times out recording at a minute.

Thanks in advance
