Start with the benchmark results and the linked PowerBI Dashboard, then compare the listed dependency changes between commits 354f8b358deba86fa37d9fca5ad80a87ac4853f3 and 3e328deefbd3029c2f957050c508b4faeee3d71f. Done means the regression is explained, the responsible area is identified, and the https and JSON benchmark results are rechecked.
