I noticed a few days ago that method backup() in PostgresNode uses pg_basebackup without specifying a checkpoint mode -- and the default is a spread checkpoint, which may cause any tests that use that to take slightly longer than the bare minimum. I propose to make it use a fast checkpoint, as per the attached. -- Álvaro Herrera
