This doesn't sound like a complaint about slow queries but rather a poor experience with pgAdmin4. The pgadmin-support@postgresql.org list is the place to voice those concerns. You will want to ensure you are using the newest patch release of pgAdmin4 as it is in active development and many fixes are happening presently, especially relating to usability and performance of the program itself.
