Hi Rémi,
During the provider creation, a lot of SQL requests are made to check a
lot of thing even if the use estimated metadata is checked :
* Fields list
* geometry type
* primary key
* extent
* capabilities (read, insert, update, delete)
You can take a look at these PRs to have an idea on all the SQL request
made at the creation :
* https://github.com/qgis/QGIS/pull/49440
* https://github.com/qgis/QGIS/pull/50186
Regards,
René-Luc

Hi Remi,
Which profiler are you talking about ?
Did you try to use the the new Debugging/Developement tool ? It's new
since QGIS 3.26 and will give you the list of requests and the time
spent for each one when loading a project/layer or opening the attribute
table.
Regards,
Julien
