[REF] account: Use a global update for each line instead of a update for each field

[moylop260]

Running a process to create too many account.move records is spent too much time.

I just get pyflame file and the SVG result is:
https://gist.github.com/moylop260/89e7703cd004485c044959f029af8423

The most consumed method is assigning fields of the method:
_compute_cash_basis

This PR improve this part.

May I ask you to give a look at this one?

Another issue that I found is that the method _compute_matched_percentage has the following depends
api.depends('line_ids.debit', 'line_ids.credit', 'line_ids.matched_debit_ids.amount', 'line_ids.matched_credit_ids.amount', 'line_ids.account_id.user_type_id.type')

odoo/addons/account/models/account_move.py

Lines 44 to 45 in 9553240

	@api.depends('line_ids.debit', 'line_ids.credit', 'line_ids.matched_debit_ids.amount', 'line_ids.matched_credit_ids.amount', 'line_ids.account_id.user_type_id.type')
	def _compute_matched_percentage(self):

Then, Do if we have added a new account_move_line all lines will be computed again and again?

UPDATE:
Worked from #31007

[nim-odoo]

update won't help you there:

odoo/odoo/models.py

Lines 4862 to 4866 in 014d61c

	def update(self, values):
	""" Update the records in ``self`` with ``values``. """
	for record in self:
	for name, value in values.items():
	record[name] = value

It does exactly what is done in the method.
