Getting the Most from Pyvorin

Top 10 practices for maximising speedup and minimising fallback.

Published May 30, 2026

1. Target Hot Functions

Use cProfile to find the 20% of code consuming 80% of CPU time.

2. Keep Types Stable

Avoid changing variable types within loops.

3. Use Supported Types

int, float, bool, list, dict, str, tuple compile best.

4. Avoid Generators in Hot Paths

Replace yield with list building where possible.

5. Pre-compile in CI

Warm the artifact cache during build time.

6. Benchmark Honestly

Measure warm runs, not cold compiles.

7. Verify Correctness

Always check correctness_match before trusting speedups.

8. Share Artifacts

Use shared cache volumes in team environments.

9. Monitor Fallback Rate

Keep fallback below 10% for maximum benefit.

10. Report Mismatches

Help improve Pyvorin by reporting correctness issues.
