Research direction

Start with src/benchmarks/micro/libraries/System.Text.Json/Serializer/WriteJson.cs at the referenced lines and run the provided benchmarks_ci.py command for the WriteJson filters. Compare the baseline and compare commits and inspect the linked benchmark and test reports to isolate the cause; done requires a validated explanation and resolution of the reported performance regressions.
