title: why my odoo server is not using all available system resources?
body: <p>I have a Vm with odoo enterprise server, working with nginx as a reverse proxy, everything works fine, longpolling, the web interface, everything is ok, but when a user tries to confirm an sales order, odoo is taking too long to finish that task, and it is not using more than 20% of CPU, it is not firing a lot of load on the DB (GCP postgres instance).</p>

  <p><a href="https://i.stack.imgur.com/X66Ns.jpg" rel="nofollow noreferrer">odoo uses 2 process only</a></p>
  <p>so, with this config, odoo is launching the process needed to match workers requested on odoo.conf, but only 2 are being used. confirming a sales order is taking too long</p>
  <p>I've tried almost everything, any help will be appreciated</p>
