@mcbouslog - a bit late to the party on this but if you are authenticated as a user, you can filter role lookups for the logged in user instead of requesting all of them and then filtering them out and checking if they are for that user. It should be quicker to fetch the requesting user roles only (if you are logged in).

Pass in the user_id you want to filter for (it can actually take a list of user ids, '1,2,3'), docs are https://panoptes.docs.apiary.io/#reference/projectrole/projectrole-collection/list-all-projectroles
relevant code https://github.com/zooniverse/Panoptes/blob/2b1e23182adb5e9b19994d4c24d020cdc6121fb2/app/controllers/concerns/roles_controller.rb#L52

Ideally we would allow you to specify which roles you want to filter for API side as well instead of filtering client side...zooniverse/panoptes#1575

Thanks! I'll refactor accordingly.
