SignalR cpu and memory efficiency

Question

How many concurrent users can a server with 8GB of memory and 3GHz of CPU handle if they are using SignalR to chat each other in a single chat room?

Answer 1

You should probably use a testing tool like "crank" to see how your particular setup performs. There are too many variables to give any finite answer as pointed out.

I believe Damian Edwards and David Fowler have done testing to get up to 150k plus connections on a single VM, but that's just a stress test and may not provide your answers. As I recall it was a very tweaked setup to do that.
