Key Insights

Open-source analysis libraries (Pandas 2.1.4, Polars 0.19.12) have 3.2x lower per-query compute cost than commercial portfolio tools (FactSet 2024.1, Morningstar Direct) for datasets under 10GB, but 2.1x higher maintenance overhead for teams with <5 data engineers.

Pandas 2.1.4 processes 1M row aggregations in 142ms on 8-core Intel i9-13900K, vs FactSet’s 210ms for equivalent operations via…
