Improving Web Application Performance - Part Three Client Side Considerations

30 May

In the first two parts of this blog series we introduced the importance of defining metrics prior to starting any performance optimization activities and the importance of identifying any user or role based issues.  In this part of the series we start to dive into the actual optimization part of the process.  I will start by introducing key concepts to look for, and then we will review the tools of the trade that can be used to help identify trouble points.  It is important to note that the information contained in this post is 100% applicable to ALL server side languages, regardless of .NET, PHP, Java, or anything else you might select to use.

Improving Web Application Performance - Part Two Users & Environment

29 May

Now that we have a set of metrics to use to validate the performance of our web application we can now start to dive deeply into resolving issues.  The first step in this journey is actually a step often overlooked by those that I encounter.  Professionally speaking 3 in 5 performance consultations that I am involved with are actually resolved by taking the points in this post into consideration.  So lets get started looking at users & environment.

Improving Web Application Performance - Part One Metrics!

27 May

For the last four or five years I have given a number of presentations on improving the performance of web applications, sometimes specifically focusing on DNN other times taking more broadly on ASP.NET.  However, the most popular of all presentations that I have given on Web Application performance was a session that took a broad look at application performance not only from a server side but also a client side application.  This talk was actually tailored to users that came from many application development backgrounds.  In this blog series I will share the information that was contained in that talk as well as a few more items of consideration that I have learned along the way.


DNN Performance: Understanding ModuleCache and PageOutputCache

26 May

Over the past 4-5 months my company IowaComputerGurus has help to optimize the performance of more than 50 different DNN based websites.  This is a major uptick in performance related inquiries as compare to past years which is to be expected as website owners become more-and-more concerned about the performance of their applications. In the current era it is important for websites to be fast not only for the user experience, but also for placement within the Search Engines.  The faster the internet connections we get the more impatient our users are when it comes to waiting for our sites to load.  Depending on who you talk to you will see metrics that show page load times of anything greater than 3 seconds can lead to lost customers & revenue for your website.  What exact e"metric you are looking to meet is up to you, but regardless a DNN based site can still easily render in sub-second times with proper configuration & maintenance.  In this post we will look into two of the most commonly overlooked configuration elements for performance the ModuleCache and PageOutputCache.
