Very interesting.

Have you tried what Peter wrote in a previous email:
1. using OPENSC_DEBUG=255 -> exact timing of APDUs

Compare a log generated on macOS with a log generated on Linux for the
same command, like "pkcs11-tool -login -O"

It would be nice to known what parts are slower on macOS than on Linux.
Maybe it is the APDU processing, maybe not.
