Opening /time_entries/new takes 10s, when we have 1000 users with 2 different groups that one has ~10 users and other has all other users.

I have looked into code and it seems I have found the issue, attaching additional info via screens. Basically if project has a lot of users assignable_users enumerates each users permissions by one, creating 2*X (X=number users) sql queries.

I'm hosting redmine with help of docker official image.
