A nice set of benchmarking data!

To answer your question, I'll analyze the latest benchmark result and provide some insights:

The three tests are comparing the performance of different cloning methods for an object graph.

**Recursive Deep Copy**

* Browser: Firefox 111
* Device Platform: Desktop
* Operating System: Linux
* Executions Per Second: 18937.603515625

This test is likely to be the fastest, as it's a simple recursive function that creates a new object with the same structure and values.

**JSON Clone**

* Browser: Firefox 111
* Device Platform: Desktop
* Operating System: Linux
* Executions Per Second: 4845.74560546875

This test uses `JSON.parse(JSON.stringify(MyObject))`, which is a built-in JavaScript method that creates a deep copy of an object by serializing and deserializing it. This method can be slower than the recursive deep copy, as it involves additional parsing and serialization steps.

**Lodash CloneDeep**

* Browser: Firefox 111
* Device Platform: Desktop
* Operating System: Linux
* Executions Per Second: 2307.508544921875

This test uses Lodash's `cloneDeep` function, which is a more efficient cloning method than the built-in `JSON.parse(JSON.stringify(MyObject))`. However, it may not be as fast as the recursive deep copy, depending on the complexity of the object graph.

Based on these results, it appears that the order from fastest to slowest is:

1. Recursive Deep Copy
2. Lodash CloneDeep
3. JSON Clone

Please note that these results are specific to Firefox 111 on a Linux desktop and may not be representative of other browsers or platforms.
