@sebastienros

Start with the fortunes_dapper, https, and json benchmark scenarios, then review the listed dependency revisions and linked commit comparisons alongside the PowerBI dashboard. Re-run the affected benchmark configurations to confirm the regression and narrow down which change accounts for it; done means identifying the cause and validating a remediation.
