Improving .NET Core Kestrel performance using a Linux-specific transport

ASP.NET Core is the web framework for .NET Core. Performance is a key feature. The stack is heavily optimized and continuously benchmarked. Kestrel is the name of the HTTP server. In this blog post, we’ll replace Kestrel’s networking layer with a Linux-specific implementation and benchmark it against the default out-of-the-box implementations. The TechEmpower web framework benchmarks are used to compare the network layer performance.

Using OpenShift to deploy .NET Core applications

Containers are the new way of deploying applications. They provide an efficient mechanism to deploy self-contained applications in a portable way across clouds and OS distributions. In this blog post we’ll look at what OpenShift brings for .NET Core specifically.

Kubernetes and OpenShift

Kubernetes is the de facto orchestrator for managing containerized applications. Google open-sourced Kubernetes in 2014 and Red Hat was one of the first companies to work with Google on Kubernetes. Red Hat is the 2nd leading contributor to the Kubernetes upstream project.

OpenShift is an open-source DevOps platform that is built on top of Kubernetes. It integrates directly with your application’s source code. This enables continuous integration/continuous deployment (CI/CD) workflows. Tools are available to scale and monitor your applications. The OpenShift Catalog makes it easy to setup middleware and databases. OpenShift comes with comprehensive documentation to install and manage your installation. It can run on-prem and on public clouds such as AWS, GCP and Azure.

ASP.NET Core Hello World Explained

Most books teaching C# start with a ‘Hello World’ application. This simple program is used to explain concepts like namespaces, classes, Main and Console.WriteLine. When every line of the code has been dissected, it’s clear how it works.

It’s less obvious for an ASP.NET Core application. We are no longer invoking our code; instead, the ASP.NET Core framework is doing that for us. In this blog post, we’ll look at a simple ASP.NET Core application and explain how ASP.NET Core makes it tick.
