When your app slows down, the first question is: who’s to blame? Is your CPU overloaded crunching numbers, or is your app stuck waiting on I/O like disk, network, or database calls? In this session, we’ll break down the difference between CPU-bound and I/O-bound processes, how to recognize them in the wild, and why the fix isn’t “one size fits all.” Through practical examples and simple optimization tricks, you’ll learn how to spot bottlenecks, choose the right strategy, and make your applications run smoother. Think of it as a detective story starring your CPU, your I/O, and you as the performance hero.
