Stop Blaming Your Framework: Your App Is Slow Because You Stopped Caring About Performance

Let me start with a confession. Three years ago, our team at Gerus-lab deployed a SaaS dashboard that took 4.2 seconds to load on a decent laptop with a fast connection. The backend was processing simple aggregation queries. The frontend was React with a bunch of libraries we "needed." The client was unhappy. We were embarrassed. We blamed webpack. We blamed the cloud provider. We blamed the data size. We were wrong. We had simply stopped thinking about what our code actually does to hardware. This is a story that's repeating itself across the industry — and nobody seems to want to talk about it honestly. Hardware Got Faster. Software Got... Heavier. Here's a thought experiment. Open a text editor built in the 1990s. It launches in under a second on a machine with 64MB RAM. Now open a modern note-taking app. It'll use 300-600MB of RAM and take 2-3 seconds to start. What changed? Not the fundamental task — you're still editing text. What changed is that we buried the actual operation un
