IIS Optimization Tutorial: Improve slow access and improve operating efficiency

Here IIS7.5 is taken as an example. Some simple operations are performed on IIS to optimize processing, improve problems such as slow access speed, and greatly improve operating efficiency.

Step 1: Adjust the IIS application pool queue length.

In the [Application Pool] list, select the application pool used by your corresponding website, and change the original queue length from 1000 to 65535. Of course, you can set the queue length here according to your own access users*1.5. For example: if you have 2000 users, you can set it here to 3000 (3000=2000 users*1.5)

Step 2: Adjust the appConcurrentRequestLimit value of IIS

Open the cmd command and run the command: c:\Windows\System32\inetsrv\appcmd.exe set config /section:serverRuntime /appConcurrentRequestLimit:100000

Step 3: Modify the ASP.NET request queue limit by adjusting processModel>RequestQueueLimit in machine.config

1. Click "Start" and then click "Run". 2. In the Run dialog box, type notepad %systemroot%\Microsoft.Net\Framework64\v4.0.30319\CONFIG\machine.config, and then click OK.

Replace the processModel element with the following value: 5. Save and close the Machine.config file.
