By default IIS7 has a limit of handling 12 concurrent requests per CPU and will queue requests above this limit. If you have some significant web load and many AJAX style requests to your server – this setting maybe very restrictive and it is hard to find out the root of the problem when you server performance is suddenly degraded.

See this post to get the picture how it can cause performance issues on your server.

Some relevant info about asp.net thread usage on IIS7 here:

asp.net thread usage on IIS7 and IIS6

Thomas Marquardt advice is to change this default limit. Recommended settings:
“All of this may be a little confusing, but for nearly everyone, my recommendation is that for ASP.NET 2.0 you should use the same settings as the defaults in ASP.NET v4.0; that is, set maxConcurrentRequestsPerCPU = “5000″ and maxConcurrentThreadsPerCPU=”0″.

This is done by adding DWORD MaxConcurrentRequestsPerCPU to the registry under

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\ASP.NET\2.0.50727.0

called MaxConcurrentRequestsPerCPU (DWORD). This key doesn’t exist by default. Or/and in aspnet.config section which overrides registry setting (also doesn’t exist by default) aspnet.config is here on windows 64bit:

%windir%\Microsoft.NET\Framework64\v2.0.50727\aspnet.config

You need to add the following section under “configuration” section (here I used default values) – don’t forget change maxConcurrentRequestsPerCPU to 5000.

< system.web>
< applicationPool
maxConcurrentRequestsPerCPU="12"
maxConcurrentThreadsPerCPU="0"
requestQueueLimit="5000" />
< /system.web>

A website’s code is like a play that tells a story to the search engine. If you have ink blotches and pages ripped or missing from the script it is hard for the search engine to understand the plot, if the search engine misses the plot it cannot tell others about it. Using rich snippets helps explain the characters and the context in which they exist making it easier for the search engine to understand. Don’t make the script too confusing or ambiguous search engine bots are not that smart, keep it simple and to the point. Make your site easy for the search engine to read and understand, and it will tell others about it. I hope to explain a little of how Microsoft tools and technologies can help you to do just that.
