CC @MichalPetryka @EgorBo PTAL the perf regression.

@JulieLeeMSFT JulieLeeMSFT added this to the 8.0.0 milestone Aug 2, 2023
@ghost ghost removed the untriaged New issue has not been triaged by the area owner label Aug 2, 2023
@vcsjones vcsjones removed the needs-area-label An area label is needed to ensure this gets routed to the appropriate area owners label Aug 3, 2023

EgorBo commented Aug 5, 2023

Only a few benchmarks in this list regressed, presumably, because of different inlining decisions - will investigate in 9.0 (or in 8.0 if I have time)
