No, it's a bit resource-intensive. A good few years ago, when I was
testing credit card auth systems for a large UK retailer, I wrote a load
tester that would sustain upwards of 200 TCP connection attempts per
second. It took me a couple of hours to write the core, and it ran on a
P100 desktop under Yggdrasil Linux, kernel version 1.0.0 - we never
found out how high it'd go, as the servers failed at a small fraction of
that load. I've no doubt far more effective DoS (and DDoS) tools exist
than that now; this is merely a datum about just how easy it is to write
better hacking tools!
