Yeah no, milliseconds matter for web, especially at scale. Amazon has a 3% drop in revenue for 300ms slower web. Yahoo got 9% traffic for 400ms. Taking Indo e-comm's public data, 300ms = 1.7T IDR drop in sales! Measure everything, never underestimate the impact of performance.
"makin susah, tapi ga makin guna" tpi kan 300ms itu penting blabaa, bacod. lu develop web, bukan develop game 🤪✌️
