General Performance: Cloning Reference, Value, and Record Types

When the need arises to clone an object, Microsoft recommends cloning an object by serializing it to JSON and deserializing it back into a new instance. I was intrigued to explore how performance varies when dealing with reference types, value types, and record types.

Performance Breakdown

When using JsonSerializer for object cloning, the benchmark results revealed clear differences across type categories. Cloning record types proved to be the most efficient.

• 1.087× faster than cloning reference types
• 1.26× faster than cloning value types

While the differences are relatively small, these findings are noteworthy and provided here for your reference.
