The comparison between scanme and nmap for syn scanning 65k tcp ports! scanme completed the scan in just 3.1 seconds, while nmap took 9.54 seconds. That's almost 3 times faster!

After another round of coding I decided to re-post. I started to implement syn scan via raw sockets (added IPv6 support)
and after a few tests I noticed that is way slower if compared to the implementation that uses pcap (without parallelism), since I am using non-blocking sockets (I found this pretty interesting)... perhaps I am doing something wrong? I tried to tune the deadline decreasing down to 1ms but in that case, I gained speed but I lost accuracy in the results of the scan. Trying to figure ways of speeding up syn scan via sockets, the best effort test on a directly connected device took about 20s to complete the scan, is that decently acceptable?

If you're interested, you can find the code for scanme on GitHub: https://github.com/CyberRoute/scanme

Any feedback or contribution is super welcome!!! Thanks in advance
