• Statistical Test threshold: 10%, the noise filter: 2 ns
• Result is conclusion: Slower|Faster|Same|Noise|Unknown. Noise means that the difference was larger than 10% but not 2 ns.
• Base is median base execution time in nanoseconds for net7.0-preview4
• Diff is median diff execution time in nanoseconds for nativeaot7.0-preview4
• Ratio = Base/Diff (the higher the better).
• Alloc Delta = Allocated bytes diff - Allocated bytes base (the lower the better)
