SetExternalServiceRepos GraphQL query takes a long time

Created by: artemruts

Description

SetExternalServiceRepos GraphQL queries take long time (~5s) on dotcom 😢

Screenshot

Notes

SetExternalServiceRepos call(s) is made when the users select and save affiliated repositories in the manage repositories view. If the user has two external services / code hosts (GitHub and GitLab) we'll have to make two (parallelizable) ~5s calls to set repositories for each of the external services.
