Introduction

Use the System Profiler to perform hotspot function analysis on Python string concatenation APIs, locate performance bottlenecks, and tune the performance of Python string concatenation based on the analysis result.

Networking Environment

This practice uses CentOS 7.6 as an example. Perform similar operations for other OSs on the Kunpeng platform.

Tuning Strategy

Analyze the hotspot functions in the application and tune the application through related functions.
Perform hotspot function analysis on the optimized application to verify the tuning effect.
