Research direction
Start by reviewing the performance examples linked from microsoft/STL#1800 and identify which operations are 20% to 70% slower than libfmt. Then locate the corresponding formatting implementation and existing performance tests or benchmarks in the repository. Done means the affected cases perform substantially closer to libfmt without regressions.
