      Description

      The current search box is very inefficient when checking for suggestions. When a user enters part of a username waiting for the autocomplete to finish, if there are a lot of users it can take a very long time.

      While running a search in the search box I ran a quick thread dump to find out where the suggest was being stuck at and found:
