Doesn't matter which framework if you implement it right. Filtering data from the dataset is plain js, and it will be slow. Rendering the data to screen requires a lot of work, such as using offscreen-buffers for smooth scrolling etc. Actually ag-grid does this pretty well, and I've used it for similar in a React app. Now hold your horses, ag-grid is angular 1.x, encapsulated as a component. Another proof that the framework is not important, you need to optimize hell out of it.
