- dman 9y agoYou will get me into trouble! I said 80x faster than the Python prototype. I did benchmark this vs Pandas over the years and depending on the usecase the two codebases trade blows with each other for static data. However for streaming datasets Perspective has a large advantage over Pandas since pandas does a full group by on every update, while perspective does its work incrementally using deltas.
