Es clave optimizar el rendimiento sin comprometer la usabilidad. Esto se logra mediante estrategias como la carga perezosa, la compresión de imágenes y el uso de caché para acelerar tiempos de respuesta. Al mismo tiempo, se debe priorizar una interfaz intuitiva con transiciones fluidas, indicadores de carga efectivos y un diseño minimalista. Además, el monitoreo continuo del rendimiento y el feedback del usuario permiten ajustes que optimizan ambos aspectos.

Simple, listen to your user. Normally speedy and usability are interconnected. You have to update each one alternately, but listen to your user to know each one you do first. And remember, I said simple, not easy. If you user doesn’t answer this question, follow your project plan, follow the product definition. Don’t be afraid of mistakes, fail fast, fail quick and cheap and you will keep this equation balanced.

Speed and user experience go hand in hand—one shouldn’t compromise the other. A fast app keeps users engaged, but a seamless, intuitive experience ensures they stay. Prioritize performance optimizations like efficient coding, asset compression, and background processing to reduce load times. At the same time, maintain a clean, user-friendly interface with smooth navigation. Test frequently to find the right balance, focusing on real user behavior. The goal is a responsive app that feels effortless to use—where speed enhances, rather than detracts from, the overall experience. Iterate, refine, and keep both elements in harmony.

In my opinion UX comes always first. I would always prioritize UX over speed if I don’t have the resources to work on both. A quick but crappy experience is not going to be tolerated by any user. Not anymore. The old belief that “as long as it works you are fine” is not a thing anymore. UX is how you get user attention, performance is how you retain him. First things first.
