Research direction

Investigate the CPU graph component's data fetching and rendering logic. Look for possible throttling or debouncing issues that cause the graph to update slowly. Check the component responsible for polling metric data from Kubernetes API and ensure it's not batching updates inefficiently. Consider whether the graph uses a library like Chart.js or D3 and if its update mechanism is optimized.
