为了弄清楚为什么 mkin 1.1.0（即将发布）测试在 winbuilder 和 r-hub 上使用 R-devel 失败，我在 Linux 上使用 R-devel 进行本地检查。我发现使用 R 4.1.2 时某些测试运行得相当快
me@computer:~/git/mkin (main)$ time Rscript -e "testthat::test_file('tests/testthat/test_tests.R', reporter = 'Progress')"

unix time 命令报告的额外时间在setup_script.R文件中花费。
当我使用本地编译的 R-devel 时，相同的测试需要四倍以上的时间

在这两种情况下，R 都使用 openblas-pthread，请参阅 R 4.1.2：

您可以尝试从我的最新提交中重现此内容（必要时增加克隆深度）
git clone git@github.com:jranke/mkin --depth=10
cd mkin
git checkout 77c248ca40b82ec00a756cd82f12968131f78959
将设置脚本剥离到从这个特定文件运行测试真正需要的内容可以减少时间差异：
$ git pull origin stackoverflow_71340826
$ Rscript -e "testthat::test_file('tests/testthat/test_tests.R', reporter = 'Progress')"
