How do people solve performance problems with GraphQL?

I can imagine that it can be quite slow internally with multiple joins/subqueries in the datastore.

It depends on how you write your joins, PostgreSQL does a great job as long as you have the right indexes in place, certainly much faster than doing sequential queries.
