ECO-CMP-PY-012 — CPU-bound work in request thread¶

Category: Computation (CMP)
Family: Python (PY)
Layer: Code
Tier: 2
Severity: warning
Tags: python, throughput, latency
Legacy ID: ECO-PY-012

Summary¶

CPU-heavy work in request handlers reduces throughput and increases latency.

Requests should stay I/O bound when possible; CPU spikes reduce concurrency.
