We recently published a BenchmarkDotNet-based benchmark on GitHub: https://github.com/DevExpress/XpoNetCoreDemos/tree/master/ORMBenchmark.
We used it to test the performance of the following Object-Relational Mapping (ORM) libraries for .NET Framework 4.6.1 and higher:
- Entity Framework 6.0.2 (EF 6);
- Entity Framework Core 2.0.3 (EF Core);
- eXpress Persistent Objects™ 18.1.3 (XPO).
