Multithreading – Whats in it ?
Dec 28
Hi,
I never took threading seriously, partly because I was barely getting started with programming let alone running and improving a Programs performance. I have all the time in the universe to wait for the program to run instead of making it run much faster 😉
Problem statement: Has 3 sites to ping, make 3 parallel pings (like opening 3 terminal and issuing a parallel ping statement) instead of one by one approach and has to be done with python
Threading Module comes to Rescue
https://github.com/yukthr/auts/blob/master/random_programs/threading_program.py
Basically, in the below output if you see two blocks, one block gets executed sequentially one ping after the other while the other one includes threading and everything is taken parallel and hence we see the output differences as well. I think am yet to figure on calculating time aspect of the threading but it is definitely faster.
Again not going much into GIL or (IO / CPU threading differences), all I can say is we can use this to enhance some day to day activities.
This may sound a little strange, macosx was not giving me any results for threading while any Linux / Unix (raspberry pi in this case) was good enough for testing the threading.

Nice article Rakesh,
I too have been looking at implementing some parallel processing in some of my network python scripts. For some reason, I am leaning more to the multiprocess module instead of threading module.
Maybe will get some time to implement this and share with you.
Happy holidays.
