Very general question.
I am a chemist by trade, but use python for a large portion of my work for data analysis. I recently upgraded my laptop from Intel i5 to i7 with double the RAM and yet Jupyter notebook (on Chrome) seems to process data at the same speed. According to Windows10 task manager I'm using 30-50% of CPU and/or GPU. They never max out even when the code is chewing through Gb of data.
Advice on how to speed things up, or what hardware upgrades actually impact processing time?
