On my Windows system I have comma as a decimal separator.
When running a benchmark these are the results I get:
// * Detailed results * BenchMark.Test1: ShortRun(IterationCount=3, LaunchCount=1, WarmupCount=3) Runtime = .NET 6.0.4 (6.0.422.16404), X64 RyuJIT; GC = Concurrent Workstation Mean = 1.163 us, StdErr = 0.006 us (0.50%), N = 3, StdDev = 0.010 us Min = 1.156 us, Q1 = 1.157 us, Median = 1.158 us, Q3 = 1.166 us, Max = 1.174 us IQR = 0.009 us, LowerFence = 1.143 us, UpperFence = 1.180 us ConfidenceInterval = [0.980 us; 1.346 us] (CI 99.9%), Margin = 0.183 us (15.73% of Mean) Skewness = 0.36, Kurtosis = 0.67, MValue = 2 -------------------- Histogram -------------------- [1.147 us ; 1.184 us) | @@@ --------------------------------------------------- BenchMark.Test2: ShortRun(IterationCount=3, LaunchCount=1, WarmupCount=3) Runtime = .NET 6.0.4 (6.0.422.16404), X64 RyuJIT; GC = Concurrent Workstation Mean = 831.283 ns, StdErr = 1.463 ns (0.18%), N = 3, StdDev = 2.534 ns Min = 829.238 ns, Q1 = 829.866 ns, Median = 830.494 ns, Q3 = 832.306 ns, Max = 834.118 ns IQR = 2.440 ns, LowerFence = 826.205 ns, UpperFence = 835.967 ns ConfidenceInterval = [785.049 ns; 877.517 ns] (CI 99.9%), Margin = 46.234 ns (5.56% of Mean) Skewness = 0.28, Kurtosis = 0.67, MValue = 2 -------------------- Histogram -------------------- [826.931 ns ; 836.425 ns) | @@@ --------------------------------------------------- // * Summary * BenchmarkDotNet=v0.13.1, OS=Windows 10.0.19044.1645 (21H2) Intel Core i7-9700K CPU 3.60GHz (Coffee Lake), 1 CPU, 8 logical and 8 physical cores .NET SDK=6.0.202 [Host] : .NET 6.0.4 (6.0.422.16404), X64 RyuJIT ShortRun : .NET 6.0.4 (6.0.422.16404), X64 RyuJIT Job=ShortRun IterationCount=3 LaunchCount=1 WarmupCount=3 | Method | Mean | Error | StdDev | |------- |-----------:|----------:|---------:| | Test1 | 1,162.9 ns | 182.91 ns | 10.03 ns | | Test2 | 831.3 ns | 46.23 ns | 2.53 ns |
As you can see in the "detailed results" the first test took 1.184 ns, the second took 826.931 ns.
But in the summary it looks like the second test IS FASTER
sorry confused us and ns. please disregard
us
ns
