Detailed Analysis
Go consistently outperforms Node.js in raw throughput and memory usage, but Node.js remains highly competitive with faster startup times.
Go's goroutine model handles concurrent connections more efficiently than Node.js's single-threaded event loop under heavy sustained load.
Connection Accept
Go accepts connections via multiple threads
Bottleneck: Node.js bottlenecked by single libuv event loop thread.
Architectural Recommendations
- Use Go for pure throughput
- Use Node.js if ecosystem and developer velocity are prioritized
Frequently Asked Questions
Why does Go use less memory?
Go compiles to native machine code and avoids V8 heap overhead.
