The batch property of the compilation element, which is enabled by default in ASP.NET, is used to control whether the initial page request will continue to compile additional files in the same directory before completing the original request. This can cause significant delay to the first several initial...

This post applies to: .NET 2.0, 3.0 & 3.5. The CLR uses an adjustable threshold property called minWorkerThreads and minIoThreads to control when to introduce throttling to thread creation. The idea behind the delay is to prevent a burst in request load from quickly creating additional threads...

Use the "throw" keyword in place of "throw ex" to perserve the original stack trace information. When you throw an exception using “throw ex” instead of “throw” you override the original stack trace with a new stack trace that starts from the throwing method. This can make tracking down the root causes...

Every now and then, you may find yourself in the situation where you need to deploy a single file on a precompiled web site. I know I certainly have. Here are the steps that I would use to accomplish this: Build and precompile your whole web site as usual; Search in the "Bin" folder of the...

Precompiling your ASP.NET web pages is a great way to increase the performance of your web site. Once your web site has been precompiled, all of the content of your .ASPX, ASMX, ASAX, etc. files will be transformed into DLLs and placed in the "Bin" folder of your web site. If you were to open one...

In the Maching.config file, there is a "deployment" element that you can add and set that will help in this area. Once set, this element will tell the ASP.NET process ignore several security and performance related settings that may have been left enabled inadvertently in the web.config and deployed...

GZip/Deflate compression will compress the response payload from the IIS web server to the browser. Pages that seem to run fast on the server but run slow over the network will see a big speed increase. I typically see around a 60% to 70% reduction in network traffic with GZip enabled. This could mean...

Review the ASP.NET Applications\Requests/Sec counter to determine how fast you are able to process work per second. Higher is better. Revew the ASP.NET Applications\Request Execution Time counter to determine how fast a page takes to execute. Lower is better. Review the ASP.NET Applications\Requests...
