If youre new to the concept of pooling you can see this => https://stackoverflow.com/questions/4041114/what-is-database-pooling, Basically what it does is reuse a database connection which has already been established instead of creating a new connection each time you make a query. So its not just a matter of prematurely optimizing, its the fact that the ORM is giving you data you dont want which you have to deal with in code.
