On mobile phone, the most simple Odoo page loads far too slowly (Odoo.sh v13)
For instance : https://www.samalife.fr/contact Page Speed Test : score 40 / 100 https://pagespeed.web.dev/report?url=https%3A%2F%2Fwww.samalife.fr%2Fcontact
And it's even worse for a normal page content including images and videos : https://www.samalife.fr/bas-du-dos Page Speed Test : score 28 / 100
The speed diagnostic points these bottlenecks :
JS SCRIPTS ( 2,4 s ) .../web.assets_common_lazy.js .../web.assets_frontend_lazy.js
CSS SCRIPTS ( 2,4 s ) .../web.assets_common.css .../web.assets_frontend.css
UNUSED CSS SCRIPTS ( 1,6 s ) .../web.assets_common.css .../web.assets_frontend.css
SERVER RESPONSE TOO SLOW ( 0,8 s )
Is there a way to improve the different aspects involved in theses slow page load on mobile : js, css, server response ?
Has Odoo.sh better hosting-packet for page loading performance ?
Has anybody tested this module? : https://apps.odoo.com/apps/modules/13.0/optimiser/
I'm encountering the same problem. These scores negatively influence the SEO.
Clean installs (runbot) get a mobile score of around 50-60..
And... How to implement asynchronous / lazy loading for css and javascript files in assets.xml ?
