Python is not that bad performer , but ....
I was delivering a session on #Rust for an #analytics team
(not mentioning the company name , dont want to disclouse their stack).
I said Rust can be 20x–200x faster than #Python for many workloads.
Someone challenged that with a real example:
15M records
Python: 44s (Using #pandas)
Rust: 39s (using #polars)
Fair question: why such a small difference?
Because in analytics, Python often isn’t doing the work.
Libraries like #NumPy / Pandas execute in #C/#C++ and vectorized code.
If the workload is already optimized or memory-bound, Rust has limited headroom.
Rust shines when:
Tight loops
Custom algorithms
CPU-bound, low-latency pipelines
Lesson learned: Changing the #technology stack can yield great results, but it’s never automatic.
#Performance depends on many factors, not just the language.
What do you say?
To prevent silent ML bugs by making data immutable, avoiding leakage, and validating every transformation before modeling.
