Enum.Equals - Performance analysis

This technical article benchmarks four methods for comparing enum values in C#: Object.Equals, Enum.Equals, instance.Equals, and the comparison operator (==). Using BenchmarkDotNet, it demonstrates that the == operator is dramatically faster (by a factor of ~100) due to the boxing overhead incurred by the Equals methods. The post explains the underlying reasons, focusing on boxing/unboxing and the internal implementation of object.Equals.
