I'll chime in with billions of data points and 100-300 feature space with some smart feature engineering outperforming DL in runtime/compute (by orders of magnitude) and performance. But the domain was very specific and everything prior to the tree was doable with matrix operations, with the tree model summarizing a mixture of experts that chose optimal features.
