Port Scanner Language Benchmark

This repository benchmarks a simple TCP port scanner written in C and Python, in order to know which language is better to write such application in future developments.

Code source:

• C: An old paper named Coding a TCP Connect Port Scanner: Step by Step by truncode security development
• Python: HowTo/Sockets from the official Python wiki at https://wiki.python.org/moin/HowTo/Sockets
• Ruby: Contribution by jbarbera 🤘
• Shell: Contribution by jbarbera 🤘🤘

Benchmark results

This benchmark has been performed using the time command in Linux to get the run time:

miguel@minidell:~/dev$ time ./portscanner 192.168.1.1
Port 23 is open
Port 53 is open
Port 80 is open
Port 443 is open

real	0m2,016s
user	0m0,000s
sys	0m0,090s

All scanning have been performed against an internal network host.

Also, three different port ranges have been used:

1. System ports: 0-1023
2. Registered ports: 1024-49151
3. Private ports: 49152-65535

Please find below the final results:

Programming Language	System ports time	System+Registered ports time	All ports time
C	0m2,016s	1m44,030s	2m16,991s
Python	0m2,244s	1m45,825s	2m19,512s
Ruby	0m2,369s	1m47,770s	2m23,626s
Shell	0m2,326s	1m50,459s	2m27,526s
