Depends largely on the bit rate of the streams and the network
connection. 5,000 streams at 32kbps is 160Mbps. A 1,000Mbps (Gig-E ) NIC
card can sustain traffic at anywhere from 160Mbps to maybe 700Mbps. I
have seen load test results for servers with results at both ends of
this range. I'm not sure what the reason for this variation is. Maybe
congestion in the network a little further outbound? You are safe
assuming that a server with a 1,000Mbps NIC can handle 5,000 streams at
32kbps, and a server with a 100Mbps NIC can handle 1500 streams at
32kbps. It's a network limitation, not a CPU limitation. I have not seen
results for a server with multiple NICs installed.
