Hello! For improving performance in a project, which general optimization techniques do you recommend focusing on? Over time, what methods have proven most effective for optimizing running functions, memory usage, and render times in your experience? Should I prioritize approaches like benchmarking, lazy loading, or code splitting? What have your experiences been with these?
What are database optimization techniques?

Guys, last year I developed a small interactive game with one of my students for a local festival. It was a sort of "let's clean up the city" simulation, and the code was running smoothly... until a group of 50 people started playing at the same time. Within the first 30 seconds, the FPS dropped to the 20s, and memory usage skyrocketed. We immediately started optimizing, and our first move was implementing a "lazy loading" approach manually.
After digging deeper into the code, we identified unnecessary repetitions in the rendering process and shifted to a "read only the necessary data per frame" logic. Then, together with the student, we broke down our code into functions that ran in stages — so, for example, while the UI was constantly updating, sound effects were only loaded when needed. When we benchmarked it, the performance jump was clear: FPS went above 60, and memory usage was cut in half. So yeah, like I said, after that chaotic moment when everyone played at once, I realized that before you start optimizing, figuring out which part is broken is the most important thing. Then, choosing the right methods becomes much easier.
