In the below method in account module, while executing the sentence:

default_account_id = obj_acc.create(cr, uid, vals, context=context)

It will take more than 10 seconds to finish which is very weird. Is there any thing we can do to improve the performance here?

def _create_bank_journals_from_o2m(self, cr, uid, obj_wizard, company_id, acc_template_ref, context=None):
