Question

My environment is: Windows Server 2008, SQL Server 2008, IIS 7, .NET 4.0, and .ASMX web service.

I am currently just using all the default settings on IIS 7 for the ASMX web service site. But I think there may be some tweaks and optimizations that probably will further improve its performance.

I found this article on MSDN though. Just not sure if it’d apply to IIS 7 as well. So what do I need to do here regarding IIS 7 settings and configurations?

Answer 1

The two main IIS 7 performance features are

• Compression

• Output Caching

“IIS 7 provides a powerful, unified facility for output caching by
integrating the dynamic output-caching capabilities of ASP.NET with
the static output-caching capabilities that were present in IIS 6.0.
IIS also lets you use bandwidth more effectively and efficiently by
using common compression mechanisms such as Gzip and Deflate”

• Configuring HTTP Compression in IIS 7

IIS provides the following compression options:
– Static files only
– Dynamic application responses only
– Both static files and dynamic application responses

• Configuring Output Caching in IIS 7

In IIS 7, you can configure output caching to improve performance on
your Web server, site, or application. When a user requests a Web
page, IIS processes the request and returns a page to the client
browser. If you enable output caching, a copy of that processed Web
page is stored in memory on the Web server and returned to client
browsers in subsequent requests for that same resource. This
eliminates the requirement to reprocess the page every time that it is
requested. This is helpful when your content relies on an external
program for processing, such as with a Common Gateway Interface (CGI)
program, or includes data from an external source, such as from a
remote share or a database.
