 Here are some benchmarks against [GORM](https://github.com/jinzhu/gorm), [SQLBoiler](https://github.com/vattle/sqlboiler) and `database/sql`. In the future we might add benchmarks for some more complex cases and other available ORMs.

-As we can see on the benchmark, the performance loss is not very much compared to raw `database/sql`, while GORMs performance loss is very big and the memory consumption is way higher. SQLBoiler, on the other hand, has a lower memory footprint than kallax, but a bigger performance loss (though not very significant in most cases).

SQLBoiler, on the other hand, has a lower memory footprint than kallax (in some cases), but a bigger performance loss (though not very significant in most cases), except for queries with relationships (that is a regression, though, and should be improved in the future).
