[Bug 1278920] Re: Bad performance when editing project members

 

** Also affects: keystone
   Importance: Undecided
       Status: New

** Description changed:

  In an envrionment with where there are more than 1000 users, edito
  project members dialog performs a query for each user to get its roles,
  which results in a bad performance. There are some alternatives to fix
  in the UI side, but we could also fix in keystone with an extension, for
  example. Please reassign to keystone if needed.
+ 
+ In the best scenario, Horizon takes 8 secs to render the UI with 1000 users and 2 assigned users.
+ On the other hand, it takes 1 min to show the UI with 1000 users and 1000 assigned users.
