Description

Originally by @Legioth


Benchmarking done in #14666 shows that elemental.json is significantly slower than org.json. Initial analysis shows that the implementation of toJson() makes up a significant amount of the time spent in json library code, and there's also lots to be gained from a more straightforward implementation of that functionality.

Research direction

Start by reviewing benchmark #14666 and the elemental.json implementation of toJson(), which the issue identifies as a significant source of library runtime. Compare the current behavior and timings with org.json, then use the benchmark results to confirm that the revised implementation improves serialization performance without changing output.
