Nick Gunn provides a practical introduction the Concurrency and Coordination Runtime for .NET. CCR radically changes the way multi-threaded applications are written in .NET, shifting the focus from threads and locks to lightweight, asynchronous tasks.
In this article, Alois Reitbauer, a Performance Architect for dynaTrace Software, specifies several architectural anti-patterns which can downgrade an application’s performance. Knowing those anti-patterns and proactively designing the application to avoid them will keep away certain snags that can impact application’s performance.
In this article, Steven Haines talks about web application performance tuning which used to be more of an art than science. He proposes a method called wait-based tuning, making the entire process more measurable and, consequently, more scientific.
