@LittleBobbyTables, oh yes, however they dont have the UI way of setting the IIS. So I thought this would be helpful. — jaxxbo, Jul 11 '13 at 18:18
you can always answer the question with your answer instead of a creating a new question and answer; it just gets confusing when there are multiple questions asking the same thing. — LittleBobbyTables - Au Revoir, Jul 11 '13 at 18:29

Using IIS this can be done. I searched everywhere, so I decided to put this out here for everyone to use this information.

Click on the server. Then on the right side pane, double click on ASP. Features view - ASP

Increase the number of threads per processor enter image description here

This doesn't appear to affect non-ASP applications. Does anyone know how to do this for ISAPI applications? http://serverfault.com/questions/531775/how-do-i-reduce-the-threads-per-process-limit-for-an-isapi-app-under-iis-7-5 – solublefish Aug 18 '13 at 00:52

This doesn't even apply to ASP.NET, it is related to just plain old ASP without .NET. – Al Kepp Feb 08 '15 at 17:30

looks like it works for ASP.NET from IIS 7.0 onwards : https://msdn.microsoft.com/en-us/library/bb470252.aspx – Imran Rizvi Sep 03 '15 at 07:23

Using config files

For example:

%windir%\Microsoft.NET\Framework64[version]\config\machine.config

<configuration>
    <system.net>
        <connectionManagement>
            <add address="*" maxconnection="24" />
        </connectionManagement>
    </system.net>
    <system.web>
        <processModel
            autoConfig="true"
            maxWorkerThreads = "100"
            maxIoThreads = "100"
            minWorkerThreads = "50"
            minIoThreads = "50" />
        <httpRuntime 
            minFreeThreads="176" 
            minLocalRequestFreeThreads="152" />
    </system.web>
</configuration>

Can this be overriden at the web.config level for a site? – Norman H Jan 07 '20 at 16:57 — Norman H, Jan 07 '20 at 16:57

This way you set number of processes, not number of threads per process. – Al Kepp Feb 08 '15 at 17:29
