IIS Server Limitations to Serve Simultaneous Connections

One of my clients concern is the number of simultaneous connections on the web server (IIS), where he published the ASP.NET web application that we just deployed recently. So here's my answer:

Actually, the IIS limit depends on the Operating System (OS) that we use:

• For Windows XP Pro, by default, that's only 10 connections, and allows only 1 site
• For Windows Vista Home Premium, by default, that's only 3 connections, and allows multiple sites
• For Windows Vista Business, Enterprise, and Ultimate, by default, that's only 10 connections, and allows multiple sites
• For Windows 7 Home Premium, by default, that's only 3 connections, and allows multiple sites
• For Windows 7 Business, Enterprise, and Ultimate, by default, that's only 10 connections, and allows multiple sites

For Windows Server 2003, 2008, and 2012, there's no limit!


What if you're running Windows XP Pro and you want to increase its number of simultaneous connections? Is it possible?

Yes, of couse. One effective technique I use is Metaedit. I just go into the metabase and change MaxConnections.

But remember, you can only assign a maximum of 39 connections using this technique!
