DDL operations very slow under macOS

Under MacOS, MariaDB appears to be an order of magnitude slower than either linux or mysql8 when executing DDL statements. Executing the attached script (simply creating/dropping a table repeatedly) gives the following results:

• macOS, mysql8: ~500ms
• linux/docker, maria: similiar, ~500ms
• macOS, MariaDB 11.2: about 5 seconds
• macOS, MariaDB 10.11: about 5 seconds

this makes running unit tests that do a lot of tight-loop DDL more or less unusable under mac/maria. Thanks for your time, LMK if you need any more info.
