For everyone that enjoyed this, there's an entire free online MIT course called Performance Engineering of Software Systems[1] where you'll learn plenty more tricks and common pitfalls like these. You'll also learn how to use tools to debug the low level performance of your programs: looking at cache misses, cpu utilization, time spent per assembly operation and so on. It's pretty cool :) [1] https://ocw.mit.edu/courses/electrical-engineering-and-computer-science/6-172-performance-engineering-of-software-systems-fall-2010/ https://ocw.mit.edu/courses/electrical-engineering-and-compu...
