I have a package that I want to submit an updated version for but the
examples run too slowly on win-builder since 4.2 came out. I just
submitted the exact same tar.gz file to all 3 versions of R available on
win-builder and got the results shown below. Notice the dramatic
slowdown from 4.1.3 to 4.2.1.
I don't know how to go about tracking down the cause of this slowdown.
The examples are quite small. I am reluctant to use \dontrun, but I am
not sure what else to do.

using Rscript and got these results: name user system elapsed

os macOS Catalina 10.15.7 system x86_64, darwin17.0 I then
installed 4.2.1 on my Mac. The time is a little slower but nothing like
the slowdown on Windows.
