ORM tools are frequently used in projects developed by object-oriented programming paradigm. Software developers generally look at the performances of these tools when they select an ORM tool. Most of the performance studies on ORM tools are limited to processing time and RAM usage information, and CPU usage information is not included. Moreover, no ORM performance study has been found in the literature, conducted in .NET 6, which is an open-source and platform-independent new generation .NET platform. In this study, to close the mentioned gap in the literature and guide the software developers, we conduct research for analyzing performances of certain ORM tools in .NET 6. Our study includes CPU usage information as well as processing time and RAM usage information. We develop a software for measuring processing time, RAM and CPU usage while performing read, insert, update, delete, search and sort operations with Dapper, NHibernate and Entity Framework Core (EF Core) ORM tools. As a result, while Dapper is best in terms of processing time for read, delete, search and sort operations, EF Core has the best results for insert and update operations. We conclude that Dapper has the best performance in terms of resource usage, while the rankings of EF Core and NHibernate vary among themselves according to the number of records and operation type.
