What rate of new connection creation can a two-router network sustain through their TCP adapters?
*165 connections per second*, measured at the TCP server. This rate was sustained with *little variation for 100,000 connections*. This took about 603 seconds. The router's memory kept growing occasionally, but it looks like it is levelling off over time just as I saw in the recent long-term soak test. The test: * The two routers are running on separate machines, talking to each other over a 40 Gbit link. * The TCP client and server are written in Go. The client connects to the server and then immediately closes the connection. The server accepts connections and immediately closes them. * The limiting factor was indeed the router network, because when the two Go programs talked directly to each other over the same link, connection creation rate was about 1200 per second.
