[8.0] pos_default_empty_image does not reduce loading time (in products with no image) about pos

[legalsylvain]

Thanks a lot for that tests, and that interesting durations !

CC : @hparfr are you using this module in production ?

Kind regards.

@JGarcia-Panach Thanks for this work.

I didn't work on the project recently so I can't do any tests now.
As far as I remember, in my setup it did accelerate the loading time in prod for all the pos (often with poor connection).

In my project, there was only few products with images (less than 10%), and other pos modules were installed.

@JGarcia-Panach : how many images requests are done when you load the pos? (as many as displayed or all products)

[legalsylvain]

Indeed, I now remember how odoo works.
images are not loaded at the beginning of the POS (as the other data), but when product are displayed. (so only the first 80 when the POS is loaded.
but after, when you do a request. (typing a char in the search box), or selecting a category, others requests will be done to the server.
So it's quite normal that this module do not reduce loading time, but yes save connection during all the use of the POS.

(you can check the server log when you use products search)
