FAPWS (Fast Asynchronous Python Web Server) is a fully WSGI compliant web server for the Python environment with 2 main objectives: keep it small and asynchronous. That way it will not heat your HW resources and will assure to not fall into C10K troubles. It can handle as much as concurrent request as your kernel can handle, Gzip support for on the fly compression and lot more.

ParSeq is a framework that makes it easier to write asynchronous code in Java. It supports Parallelization of asynchronous operations (such as IO), Serialized execution for non-blocking computation, Execution tracing and visualization, Tasks with retry policy, Code reuse via task composition and lot more.

ReactiveMongo is a scala driver that provides fully non-blocking and asynchronous I/O operations. It allows you to stream data both into and from your MongoDB servers.

Tide is a friendly HTTP server built for casual Rustaceans and veterans alike. It's completely modular, and built directly for async/await. Whether it's a quick webhook, or an L7 load balancer, Tide will make it work. Each Tide endpoint takes a Request and returns a Response. Because async functions allow us to wait without blocking, this makes Tide feel similar to synchronous servers. Except it's incredibly efficient.

EA Async implements Async-Await methods in the JVM. It allows programmers to write asynchronous code in a sequential fashion. It is heavily inspired by Async-Await on the .NET CLR. EA Async should be used to write non-blocking asynchronous code that makes heavy use of CompletableFutures or CompletionStage. It improves scalability by freeing worker threads while your code awaits other processes; And improves productivity by making asynchronous code simpler and more readable.

TymeacRSE is a Recursive Streams push engine for managing the publication and distribution of items to subscribers. An efficient push engine allowing (Reactive Stream) Publishers to generate asynchronous streams for routing to Subscribers. It provides an efficient multitasking service that allows many resource-intensive applications to coexist in a single microservice.

A screamingly fast, ultra-lightweight WSGI server for CPython, written in C using Marc Lehmann's high performance libev event loop and Ryan Dahl's http-parser. It is single threaded and it has less memory foot print.

Monix is a high-performance Scala / Scala.js library for composing asynchronous and event-based programs, exposing high-level types, such as observable sequences that are exposed as asynchronous streams, expanding on the observer pattern, strongly inspired by ReactiveX and by Scalaz, but designed from the ground up for back-pressure and made to cleanly interact with Scala’s standard library, compatible out-of-the-box with the Reactive Streams protocol.

libco is a cooperative multithreading library written in C89. Although cooperative multithreading is limited to a single CPU core, it scales substantially better than preemptive multithreading. For applications that need 100,000 or more context switches per second, the kernel overhead involved in preemptive multithreading can end up becoming the bottleneck in the application. libco can easily scale to 10,000,000 or more context switches per second.

Asio is a cross-platform C++ library for network and low-level I/O programming that provides developers with a consistent asynchronous model using a modern C++ approach.

Mutiny places events at the core of its design. With Mutiny, you observe events, react to them, and create elegant and readable processing pipelines. Mutiny is the perfect companion to tame the asynchronous nature of applications with non-blocking I/O. Declaratively compose operations, transform data, enforce progress, recover from failures and more. 
<BR><BR>
 Mutiny can be used in any asynchronous application such as event-driven microservices, message-based applications, network utilities, data stream processing, and reactive applications.
