I am trying to test the limit of a Windows Server 2008 (64 bit with 15 GB RAM) machine for maximum inbound TCP/IP connections on a port. I am using C# with async sockets.
The issue I am facing is that server stops accepting more after 90-100K TCP connections even though of resources are still free (CPU, memory). There is no fixed limit after which is stops but it is in range of 90-100K and sometime even little more than that.
Does anyone have idea about this issue?
How many maximum TCP connections ever achieved on windows machine?
