Flask

Compile hot route handlers:

from flask import Flask
app = Flask(__name__)

def heavy_computation(n):
    total = 0
    for i in range(n):
        total += i * i
    return total

@app.route('/compute/')
def compute(n):
    return {'result': heavy_computation(n)}
pyvorin run app.py --function heavy_computation

FastAPI

Pre-compile service functions for faster request handling:

from fastapi import FastAPI
app = FastAPI()

def process_data(data):
    return [x * 2 for x in data]

@app.post('/process')
def process_endpoint(data: list[int]):
    return process_data(data)

Django

Compile utility functions used in views or management commands:

def aggregate_metrics(records):
    totals = {}
    for r in records:
        key = r['category']
        totals[key] = totals.get(key, 0) + r['value']
    return totals

Deployment Notes

  • Compile during build time, not at request time.
  • Cache compiled artifacts in the container image.
  • Use --no-fallback in CI to catch compile failures early.
