There are several problems with ASP.NET MVC application when deployed on IIS 6.0: Extensionless URLs give 404 unless some URL Rewrite module is used or wildcard mapping is enabled IIS 6.0 built-in compression does not work for dynamic requests. As a result, ASP.NET pages are served uncompressed resulting in poor site load speed. Mapping wildcard extension to ASP.NET introduces the following problems: Slow performance as all static files get handled by ASP.NET and ASP.NET reads the file from file system on every call Expires headers doesn't work for static content as IIS does not serve them anymore. Learn about benefits of expires header from here . ASP.NET serves a fixed expires header that makes content expire in a day. Cache-Control header...

At times even after applying the best coding policies & practices you don’t get the desired level of performance you are hoping from your ASP.NET application. This is because there are number other very important factors that directly affect ASP.NET applications. To get the best out of any system requires detail architectural, design, coding and deployment considerations. The post lists few of some of the many performance tweaks that you can implement to boost up ASP.NET performance. Remove Unused HTTP Modules There are various HTTP modules in ASP.NET that intercept each request sent to the server. Session State is a very commonly used HTTP module used to load session data in context object. It’s referred with SessionStateModule name. HTTP...

Each day we all use everyday things to accomplish everyday tasks. For programmers our everyday tools are arrays, loops and OOP constructs. We all use them, but are we all aware of the performance implications? In his talk, The Performance of Everyday Things, Jeffery Richter asks the question, "Do you know what goes on under the hood in .NET?" Performance of an application impacts user experience in dramatic ways. When software is slow user’s frustrations soar and create an anxious user experience. In this podcast our guest, renown author , consultant and co-founder of Wintellect Jeffrey Richter sheds some light on how everyday programming practices can have a significant effect on application performance. Listen to the Show Interview...

I'll be presenting at the Northwest Ohio .NET User Group this evening at 6pm. The talk will be a slightly modified version of my Black Belt ASP.NET Performance talk that I gave earlier this month at Tech Ed in Orlando. According to their web site, the user group will also be giving away a Zune to one of the attendees of tonight's meeting (and I have a book and some shirts, too...), so if nothing else, you can come for the free stuff. The main topics covered in this talk are performance testing with load testing tools, caching, and asynchronous programming.

Interested in knowing what kind of performance gains you can expect from IIS7?  Performance is a fickle beast, with so much of it dependent on your application, your hardware, configuration and tuning... it is sometimes hard to know which variables carry the most weight.  Fortunately, the Microsoft.com operations folks have put together a great summary of their real-world performance data .  The short story is: IIS7 servers handle 31% more requests per second than their IIS6 peers...( read more ) Read More...
