UUID in MySQL isn't a built-in type, it relies on a function call, so the likeliest cause of your insert performance issue is the UUID column. If it's me, I test that possibility by benchmarking against the same table with an auto_inc key.

If you really need UUIDs, see https://www.percona.com/blog/2019/11/22/uuids-are-popular-but-bad-for-performance-lets-discuss/ re dealing with UUID performance issues.
