Memory: 16 GB
CMake Build Type: RelWithDebInfo
Run Env => thread number: 1
Note: The MSVC (Visual Studio 17 2022) job logs were truncated by GitHub, so results
from the MinGW-w64 windows-latest build are shown here. Each case ran with its
default arguments (100000 coroutines/tasks, 10000000 switch operations).
Binary names are abbreviated (bin/libcopp_sb* = sample_benchmark_*); the category
of each case is described in its "######" header line.
