odd changes in it/s when changing input a/o settings

[telejoshi]

Hello everyone!
I'm not very experienced in Python, so I'm clueless. Here's some data of test runs:

• 50MB address.txt, running on "30 cores" (30 threads) - ~650 it/s
• 50MB address.txt, running on "16 cores" (16 threads) - ~660 it/s

/edit: With 30 cores CPU is at 95% and with 16 cores around 50% (just as you would think) but it/s seems to be the same. How is that possible?

RAM usage is ~8GB so not a problem when using small address.txt and 30 threads.
However, when I use the big file it will only work with 18 threads max, because then my 32GB RAM (!) are full ;)

Greetings
