I've done some very/extremely basic tests that suggest that this won't scale very well, and I don't think NSE is the problem. But like I said, the tests are very basic, and as always I may be very wrong :) Running the following command against a server listening on the loopback interface takes roughly a second: ncat/ncat 127.0.0.1 9929 < /dev/zero Running the same command ten times in a row, takes roughly 10 seconds. Running ten times in a row in two separate terminal windows increases the time for each sequence of ten connects to 20 seconds. Three terminal windows result in 30 seconds.... //Patrik Den 2011-03-13 12.28 skrev Toni Ruottu <toni.ruottu () iki fi>:
Oh boy. I am lost. It does not use 100% cpu, it does certainly not use the full network bandwidth, and there is no way it could use up all memory. Now, what other bottle necks are there?
