Slide own by odoo, spreading show off, their material fake, their stable version hold a lot bug even basic bugs too. can't trust on them who delete own tweets. We not only use it but also keep working on development and r&d, we had large database, for large database odoo is not physical, but even for small database their are issues. Odoo is ultimate tiny ERP, its even with few many binary fields as relation and form stuck for loading, Not talking about tiny ERP, its highest performance, I had seen other people also facing same troubles.

As far as it was possible to understand your language, I tried to help, but you seem not to be looking for help...
