Take a look at the docs specifically about the attributes maxToRenderPerBatch,updateCellsBatchingPeriod and removeClippedSubviews. In your case, it's rendering 50 items per batch of render, the updateCellsBatchingPeriod maybe is making the list update itself longer than expected and maybe if you set the prop removeClippedSubviews to true the list is going to stay fluid as you want.
