Middleware Performance

Middleware Performance Example

Compare performance impact of different middleware configurations.

Running

go run main.go

Server starts on http://localhost:3004

Benchmarking

Use ApacheBench to test performance:

ab -n 1000 -c 10 http://localhost:3004/baseline
ab -n 1000 -c 10 http://localhost:3004/light
ab -n 1000 -c 10 http://localhost:3004/heavy

Endpoints

• /baseline - No middleware
• /light - 1 lightweight middleware
• /light-5 - 5 lightweight middleware
• /heavy - 1 heavy middleware (10ms delay)

Key Insights

• Middleware overhead is minimal for simple operations
• Multiple lightweight middleware have negligible impact
• Heavy processing in middleware directly affects response time
• Keep middleware focused and efficient
