Get GOing with a New Language
summary
Rewrites a 2,000‑line messy PHP4 app into Go and cuts downtime: emails backlog falls from ~5,000 to almost zero and processing completes in about two seconds. Shows performance numbers (Go ~4,500 req/s vs PHP ~1,800–2,500 in cited benchmark), uses goroutines and channels for concurrency, implements a worker pool with sync.WaitGroup, and relies on built-in tools like go build/go run/go fmt plus the race detector and modules. Results: simpler error handling, faster runtime, and easier dependency management.
