Describe the bug

I've got a lot of such messages when retrieving stacks of a board:

"app":"deck","method":"GET","url":"/index.php/apps/deck/stacks/10","message":"Controller OCA\\Deck\\Controller\\StackController::index created 140 QueryBuilder objects, please check if they are created inside a loop by accident.","userAgent":"Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:94.0) Gecko/20100101 Firefox/94.0","version":"22.2.0.2"}
"app":"deck","method":"GET","url":"/index.php/apps/deck/stacks/10","message":"Controller OCA\\Deck\\Controller\\StackController::index executed 140 queries.","userAgent":"Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:94.0) Gecko/20100101 Firefox/94.0","version":"22.2.0.2"}

Is it normal?

To Reproduce
Steps to reproduce the behavior:

1. Go to Deck's web interface and open a board with 10+ cards

Expected behavior
In an ideal world such messages should not appear imho. At least messages recommand to check if the QueryObjects aren't created inside a loop by accident. So, I think it's worth creating an issue.

Screenshots
No screenshots, everything seems to be working ok appart from these messages

Start at OCA\Deck\Controller\StackController::index for GET /index.php/apps/deck/stacks/10 and reproduce the request on a board with 10+ cards. Check whether the reported QueryBuilder and query counts are expected, then document or address the cause so opening the board no longer produces unjustified performance warnings.
