Spent the day taking care of a super old #Odoo 8 instance that just migrated to a new hosting, and performance suffered a lot. Things that were not optimal, degraded to unusable.
One key issue: a wizard that was created as a draft record and was receiving lines as default values (from records linked on the active record from which the wizard was launched). Each line of the wizard has 3 m2o fields.
