Benchmarks for candidate algorithms for System.String.Repeat.
dotnet run -c Release -- --statisticalTest 5% -f "*"--statisticalTest 5%performs the Mann-Whitney U test with a 5% significance level.- If you change it to 10%, slighter differences in results will be treated as statistically significant.
- If you want to run a specific benchmark, you might want to replace
-f "*"with-f "<benchmark name>*".-f "*"runs all the benchmarks, which results in the consumption of a large amount of time. - If you feel like this benchmark takes too long to run, you might want to add
--maxIterationCount 50(or less value) to the command above. - If you want to add or change runtimes, you might want to add
-r <baseline runtime> <another runtime #1> <another runtime #2>. - If you want to preserve past results, you might want to add
--noOverwriteto the command above.
The results are stored in ./BenchmarkDotNet.Artifacts/results/.
Command:
dotnet run -c Release -- --runtimes net8.0 nativeaot8.0 --statisticalTest 5% -f "RepeatDoubleBlockSizeBench*" --noOverwrite -mResults:
