Watchers pop up window appears after a long time

patch #33329 introduces a performance issue
When you want to add a watcher to an issue in a project with many collaborators, the pop-up window take between 10 sec and 20 sec (according to the number of collaborators) to appear.
It's very disturbing because user has no graphical indication about that.

- Related to Patch #33329: Improve watchers functionality to mark the users that are watching a non visible object and to not return watchers that cannot see the object added
How many members do you have on the project where you experience this issue? (rounded number).
In #33329, I've proposed two options (4 and 5) to avoid this performance issue, which one works better for you?
when it took 10 seconds to pop up, there is 900 members.
when it took 25 seconds, there is 2500 members.
I prefer the option 4
Thank you for the patch #33329 that is good improvement for sure.
But we do have the same perfomance problem with 1300+ users.
is making at least two SQL queries per user.
I don't think we need all users names listed when the search query is blank. so I would like to request option 4.
As a test, I made this change and it reduced loading time from 4 sec to 0.2 sec.
- scope = @project.principals.assignable_watchers
+ scope = @project.principals.assignable_watchers.limit(100)
We have the same problem that watchers pop up window appears after a long time.
Redmine version 4.2.8.stable
Ruby version 2.7.6-p219 (2022-04-12) [x86_64-linux]
Rails version 184.108.40.206
Database adapter PostgreSQL
Mailer queue ActiveJob::QueueAdapters::AsyncAdapter
Mailer delivery smtp
We have 3 000 users and when we want add watchers for an issue, it takes a while to appear the watchers box (20 seconds).
Is there a solution ?
- like limiting watchers for a project ...
Thank you for your help.
