### Asynchronous programming in .NET by Gerardo Lijs Twitter @GerardoLijs April 2019 ## Content What is Asynchronous Programming CPU-bound vs IO-bound Obsolete patterns Tasks and async/await Practical Count(n => Enumerable.Range(2, (int)Math.Sqrt(n) - 1).All(i => n % i > 0)); } ## Asynchronous method Task GetPrimesCountAsync(int start, int count) { return Task.Run(() => of the time you will need asynchronous to deal with IO-bound operations and the times you will use CPU-bound operations you will probably use a library that provides asynchronous methods for you to interact

flexible setup. ## 5 What's new in Zabbix 7.0.0 See breaking changes for this version. Asynchronous pollers New poller processes have been added capable of executing multiple checks at the same pollers are asynchronous - they are capable of starting new checks without the need to wait for a response, with concurrency that is configurable up to 1000 concurrent checks. Asynchronous pollers have parallel checks while waiting for network response, and the new pollers do that. You can start asynchronous agent pollers by modifying the value of StartAgentPollers - a new server/proxy parameter. HTTP

Tornado [https://www.tornadoweb.org] is a Python web framework and asynchronous networking library, originally developed at FriendFeed [https://en.wikipedia.org/wiki/FriendFeed]. By using non-blocking listen(8888) tornado.ioloop.IOLoop.current().start() This example does not use any of Tornado’s asynchronous features; for that see this simple chat room [https://github.com/tornadoweb/tornado/tree/stable/demos/chat] with only one thread per process. See the User's guide for more on Tornado's approach to asynchronous programming. While some support of WSGI is available in the tornado.wsgi module, it is not a
