So what you're saying is that you should save the 10$ from the 15$ you pay for a Cortex and instead spend many many days to end up with a outlandishly slow solution?

I take it this is supposed to inspect network traffic, at some point you need some raw throughput.

I don't know where you got those numbers from. The savings difference (after buying the needed hardware for networking, etc. for the non-comprehensive solution) would be along the lines of a hundred dollars (if not closer to 150).
