Hi gotaquestion,
But now I needed to expand my concurrent connections to my app. So I purchased some new hardware and Windows Server Essentials 2012.
I just setup my signlar app and started opening up browser windows to test it on the new box and I couldn't get more than 4 connections open at once. The fifth browser page just hangs. as soon as I close another browser page the hanging page appears.
As far as I know, the IIS8's default MaxConnections is 4294967295.
So I don't think it is the reason why the browser page hangs.
I suggest you could check the IIS advanced settings.
More details, you could refer to follow image:

Best Regards,
Brando
