The best answer is “test to a limit at which you’re comfortable for your application.”


Any advice on how to do this?
I’d be comfortable with a 1000 calls simultaneously…

Find a server, lab up your application and start testing. If you’re not getting enough calls, go get a more powerful server, or split your workload between multiple servers.
