Quick smoke test. How big are your requests/responses? You mention
REST, which implies they're going to be based on HTTP. I would expect
you would have some idea of the rough size. Multiply that by 50,000,
and see whether your connection can handle it. For instance, if you
have a 100Mbit/s uplink, supporting 50K requests/sec means your
requests and responses have to fit within about 256 bytes each,
including all overhead. You'll need a gigabit uplink to be able to
handle a 2KB request or response, and that's assuming perfect
throughput. And is 2KB enough for you?
