Is ORM slower than raw query?
Long story short: for anything but the most basic of queries, ORMs require multiple queries to fetch all the data you need. This, more than anything else, is why ORMs are perceptually slower than raw SQL.
Do you need ORM for MongoDB?

Is ORM bad for performance?
Yes, ORM will slow down your application. By how much depends on how far the abstraction goes, how well your object model maps to the database, and other factors. The question should be, are you willing to spend more developer time and use straight data access or trade less dev time for slower runtime performance.
Does ORM improve performance?
An ORM can provide many benefits to development speed, code readability and can remove a lot of code repetition.
Is MongoDB ORM or ODM?
MongoDB is an example of a document database – you would use an ODM to translate between your objects in code and the document representation of the data (if needed). Mandango is an example of an ODM for MongoDB. You can have hybrid ORM/ODM frameworks, like mORMot for Delphi, Doctrine for PHP or Hibernate OGM for Java.
Can ORM map the NoSQL database?
Many ORM standards (like JPA and JDO) were written for relational databases that don’t always provide ways of doing certain things in NoSQL. In fact, most of the ORM tools (like hibernate) were built to solve only 80% of the frequently used mapping problems.

If you know your data access pattern is going to be complex or you plan to use a lot of database-specific features, you may not want to use an ORM.
