Benchmarking

It is 2025, and the debate between Rust and Go for backend web development has shifted from “which is cooler” to “which fits the specific engineering constraint.” Both languages have matured into industrial powerhouses. Go has cemented itself as the language of the cloud infrastructure (Kubernetes, Docker), while Rust has infiltrated the Linux kernel, high-frequency trading, and massive-scale web services at companies like Amazon and Microsoft.

In the landscape of 2025, Python remains the dominant language for data engineering, AI orchestration, and backend web services. With the maturation of the No-GIL CPython (introduced experimentally in 3.13 and stabilized in subsequent versions), threading performance has skyrocketed. However, one fundamental constraint remains: Memory.
