### AI overview

This tutorial explains how time complexity and memory usage affect application performance as input size, system scale, and traffic increase. It introduces Big O notation, compares common complexity classes, and discusses trade-offs involving algorithms, data structures, and memory, with examples in Go and C.

### Source excerpt

Memory usage and time complexity shape the performance of every application. This post explains why they matter, how they affect scalability, and how to think about the trade-offs behind every decision.
