Python Code Optimization (To Run Faster)

I have a python code that I wrote that does the following: opens browser with a proxy, goes to website login, puts in username and password, logs in, goes to a designated page and removes some things off page so it can process faster. I have it doing these in a repeated fashion to run 50+ instances of these. My goal is to open up to 150-200 instances of these in less than 30 minutes. In order for my code to work well, I upgraded my pc to a new proccessor from i5 to i7 and in every way its suppose to be faster or better than the i5. With the upgrade to the i9, it can open more instances bui runs slower. I tested it by opening a browser and the internet connection is so much slower. So to even open 50 it takes a whole hour compared to when i had the i5 it opened 50 in less than 30 minutes. I am not sure what is wrong. I tested the code by sending it to a page that doesn't use any updating scripts while running multiple instances of it also, but it is still way too slow. I believe the code needs optimization so it can run faster. Look forward to elaborating.
