@Yenthe: Can you describe what was slow about it? Was it any interaction with the UI or how did this affect you? 

How many unseres did you have on it and how many workers did you set up? 

Thanks in advance!

Hello ! We are on odoo.sh since January (V15 Entreprise) with about 15 concurrent users. Some days it's so slow it's bearely usable. I dont' if there someting wrong with our instance... Is sh still as slow as @yenthe said in 2018 ? Does it still need tweaking the code as mentionned by Ray Carnes ? When I open a ticket with odoo about it, they say I should clear the borowser's cache... 

@Yenthe : Is there a way to improve the different aspects involved in slow  page loading on mobile : js, css, server response ?

• How to implement lazy loading for css and javascript files

• Does Odoo.sh provide alternative hosting packets for higher performance ?

• Has anybody tested this module? : https://apps.odoo.com/apps/modules/13.0/optimiser/

While it is hard to give generalized advice on sizing (it depends on how many users you have using the system at the same time [concurrently] and what those users do) we currently recommend 1 worker for every 25 users (about 6 concurrent users).

Note that a user is only connecting to the server when they click a menu or button.  In most cases when they are typing or reading, they are not connected (except when they type and the server tries to autocomplete a search result).
