I can’t count the number of of times where a beginner did some stuff in pyroot that was horrifically slow and just implementing the exact same algorithm in C++ was two orders of magnitude faster.

If you don’t use RDataFrame, or it’s just histogram plotting, be very careful with pyroot.

You should be using RDataFrame though, or awkward + dask.

+1 for RDataFrame for what it can do. Just be prepared to bail to C++ and for loops when you exceed what it can do without major headaches.
