 The duration of the test can be tweaked by changing the number of iterations in the `[InlineData]` in the `PerformanceTest` class.

-It is followed by a `pushd` command into the artefact directory, and a command to run coverlet.  Run these to get to see the coverlet output and especially the test duration. E.g.:

 To run with a development version of coverlet call `dotnet run` instead of the installed coverlet version, e.g.:
 
-    dotnet run -p C:\...\coverlet\src\coverlet.console\coverlet.console.csproj -c Release -- "System.Collections.Concurrent.Tests.dll" --target ...
