Python has evolved since Flask was first released around 8 years ago, particularly with the introduction of asyncio. Asyncio has allowed for the development of libraries such as uvloop and asyncpg that are reported (here, and here) to improve performance far beyond what was previously possible. Sadly Flask is not easily combined with asyncio or these libraries. However the Flask-API can be used with asyncio via the Quart framework.
