The post compares Node.js and Go, focusing on raw execution speed, concurrency capabilities, and HTTP request handling. Go outperforms Node.js in speed due to its compiled nature and efficient memory management. Both Node.js and Go handle concurrent I/O tasks well, but Go scales better under heavy CPU loads. Go is significantly faster in HTTP benchmarks, benefiting from its goroutine-based concurrency model. While Node.js offers flexibility and rapid development, Go promises better scalability and predictable performance.

Performance Benchmark: Node.js vs Go

Compiled vs Interpreted language is and unfair comparison.

The article compares node’s express package with go’s fiber to benchmark http requests. Do I need to say more?

It’s like comparing a screwdriver to a french wrench.

This is a waste of time to compare. It doesn’t really matter the performance curves move downwards as you add business logic, API calls to other services, DB data requests, etc… In then end what maybe you handle twice as many requests, if you are lucky, but I can scale that with another K8s node for 99.999% of applications and write it faster in Node.js then Go. If you are Facebook, Amazon, Google that is a different story. Also I have a feeling this engineer has no clue how Node.js really works.
