We can but guess, but... Quite possibly your laptop is not actually a
poorer machine for single uncomplicated queries. If it's cores are
faster than the test servers, than your laptop would out-perform the
server for such queries.

Once you get other users starting to run queries as well, turning the
load into a parallel load, the server will probably turn out faster
again.
