Code runs slow but multiple python IDEs makes it faster
<p>I have a simple webcrawler which crawls ~4 (specific) sites per second. If I run the script in tow different python IDE's I can double the speed because both programs runs the code with ~4 crawls per second. 
Why does my code runs slower then It could be? Or is it faster because I use a silly way to make my script use multithreading/multiprocessing by using two different IDE's at the same time?</p>

<p>I use Python 3.5.2</p>

<p>This sounds like a great task for a Pool of worker threads.</p>
