The Crisis of "Slow Data"

In the high-stakes worlds of Fintech and Global Sales, a three-second delay in dashboard rendering isn't just an inconvenience--it's a critical failure in decision-making. Most modern BI solutions rely on heavy third-party libraries that bloat the DOM and choke under the weight of real-time data streams.
