Using for Python TCP ping, time measure difference from other tools? - python-3.x

Question

I am trying to write a simple tool that measures the TCP port open, the code works well.
The issue I have is that when I compare the TCP ping result to other tools, such psping (Sysinternals), tcpping , check_tcp(Nagios), I get much lower results than my code.
In my code open TCP port open takes around 9~10ms, others tools takes 0.200~0.500ms
in the beginning, thought its related to the case if I have multiple interfaces on my computer, I added to bind to the correct interface and didn't change the results.
In addition, i found that the difference between python and other tools, I used Wireshark to capture both python and psping, and I found that
the final handshake from client side FIN, ACK is much slower in Python than psping and that is the difference the 10ms.
Is there any flag in Python TCP to make it faster?
My question is, why I get such different results?
Please advice
Thanks

as suggested post from babygame0ver solve the "latency" issue added threading and latency now much other tools
Thanks
