IIS Configuration

Max concurrent requests per application

Increase the number of concurrent requests IIS will server at once:

• Open %windir%\inetsrv\config\applicationHost.config
• Locate the serverRuntime element
• Add the appConcurrentRequestLimit attribute if not already there and set it to a suitable number (5000 is the default in IIS7+)

e.g. <serverRuntime appConcurrentRequestLimit="250000" />

ASP.NET Configuration

Request Queue Limit

Increase the request queue limit that affects how many concurrent requests ASP.NET will process:

• Open %windir%\Microsoft.NET\Framework\v4.0.30319\Config\machine.config
• Locate the processModel element
• Set the autoConfig attribute to false and the requestQueueLimit attribute to a suitable number

e.g. <processModel autoConfig="false" requestQueueLimit="250000"/>
