We are searching for a cluster solutions for postgresql, we need to increase our current psql server performance running under ubuntu 14 v9.3.
The db is for odoo 7.x
I have some experience with odoo 7.x - there are lot of pretty slow queries without good possibility of optimization. More - there are some articles on net that advices suboptimal configuration of Postgres, of odoo.
If you can, you can try to upgrade to PostgreSQL 9.6 - more CPU per query can help, or you can upgrade to new odoo (I have not real experience, but the web speak about lot of optimization).
If you have some own customization, look to slow queries - lot of performance issues can be fixed.
