asyncio Description
Asyncio provides a foundation for many Python asynchronous frameworks. These include high-performance web and network servers, database connection libraries, task queues distributed across multiple computers, etc. Asyncio can be a great fit for IO bound and high-level network code.

FastAPI
FastAPI is an advanced web framework that allows you to build APIs using Python 3.7+. It uses standard Python type hints. Fast: Very high-performance, on par with NodeJS or Go (thanks Pydantic and Starlette). One of the fastest Python Frameworks available. Reduce code duplication and get multiple features out of each parameter declaration.

Koa
Express's new web framework Koa was created by the team behind Express. It aims to be a smaller and more expressive web framework that can be used to build web applications and APIs. Koa leverages async functions to eliminate callbacks and improve error handling. Koa doesn't bundle any middleware in its core. It provides an elegant suite that makes writing servers fast and fun. A Koa application is an object that contains a collection of middleware functions. These functions are composed and executed in a stack-like fashion upon request. Koa is similar in design to Ruby's Rack and Connect. However, Koa provides high-level "sugar", at the low-level middleware layer. This increases interoperability and robustness and makes middleware writing much more enjoyable.

Tornado Web Server
Tornado is a Python web framework that also includes an asynchronous networking library. It was originally developed by FriendFeed. Tornado uses non-blocking network I/O to scale to thousands of open connections. This makes it ideal for long polling and WebSockets as well as other applications that require a long-lasting connection to each user. Tornado is a Python web framework that is unique. It does not use WSGI and is usually run with one thread per process. Although some support for WSGI is provided in the tornado.wsgi module it is not a main focus of development. Most applications should be written to use Tornado’s own interfaces (such WSGI directly) instead of using WSGI. Tornado code is not thread safe. Tornado is integrated into the standard library asyncio and shares the same event loop (by default, Tornado 5.0). Libraries designed for asyncio use can be used with Tornado.

GraalVM
Native Image allows you to discover libraries and frameworks that work right out of the box. Native Image is an advanced optimizing compiler that generates faster, leaner code and uses fewer computing resources. To ensure Java applications run instantly and provide peak performance, you can compile Java applications in advance. You can leverage the best features and libraries from popular languages in one app. Monitor, profile, and optimize Java and other languages' resource consumption. GraalVM's JIT compiler produces optimized native code that runs faster and produces less garbage. It uses less CPU due to a variety of compiler optimizations and aggressive inlining techniques. Applications that run faster and use fewer resources will be the end result, which can reduce cloud and infrastructure costs.
