Async python is faster when you use it for running parallel tasks. In this benchmark, you are running a single database request per query, so there is no advantage to being asynchronous: a pool of processes will scale just as well (but it will use more memory). The point of async is that it lets you easily make a Postgres query, AND an HTTP query, AND a redis query in parallel.
