Performance and scalability (.Net)

A couple of years ago, I was part of a team re-developing a system in C# to fix some performance and scalability issues. At the time, I was familiar with some basic techniques with C# and Database programming to increase performance and scalability. When discussing the topic with a colleague, he recommended reading Microsoft's white paper on Improving .NET Application Performance and Scalability - It really helped me out. A word of warning: The white paper is rather long, and took me weeks to get through. Also, it hasn't been updated since it was released in early 2004 to include a lot of the newer technologies I'm now using with .Net. However, I've often referred back to it when designing a new application or system, or when confronted with a performance problem.
The reason I like this white paper so much is that it's organized well, and doesn't skimp on the technical details. A core theme of the white paper is setting goals, measuring baseline performance, and measuring performance after making changes. This fundamental technique is critical in developing high-performing and scalable systems, and it's surprising to me how often it's overlooked.
This white paper is one of a number of initiatives I've been impressed with from the Patterns and Practices group. It would be even better if they would just keep it up to date.

  1. That whitpaper may have been good in 2000, but it's all out of date now
