The test results show that FusionAuth can handle a large number of entities, with hundreds of millions of entities and a significant number of users. The system performed well even when pushing entity data into a token during a login. However, retrieving entity data in a lambda resulted in a 11.7% decrease in the number of logins per second. Disk space issues were also encountered, particularly when loading and indexing large amounts of entities. Despite these challenges, FusionAuth demonstrated good performance and responsiveness even with such a large amount of data.
