Python vs. Go: A Tale of Two Web Servers and Astronomical Resource Differences
2025-03-08
This article compares a simple FastAPI (Python) and Go web server, highlighting Python's excessive resource consumption in production. The Python Docker image is significantly larger than the Go equivalent, requiring orders of magnitude more RAM. This leads to higher server costs and operational complexities. Further, Python code maintenance and upgrades present challenges, such as GIL limitations, exception handling, and package dependency upgrades. The author uses personal experience and industry examples to illustrate the impact of language choice on project costs and engineering efficiency, suggesting Go or similar lightweight languages for resource-constrained or performance-critical applications.
