Your SQL Is Fast but the API Is Slow: It's the Ruby Layer

1. 1Analyze database query performance to rule out SQL bottlenecks
2. 2Profile Ruby application code to identify slow methods and functions
3. 3Optimize serialization and object allocation to reduce GC pressure
4. 4Apply memoization techniques while avoiding common gotchas
5. 5Test and benchmark API performance after optimizations

Backend engineers and developers who work with Ruby on Rails can benefit from understanding these performance issues to improve API speed and overall application efficiency

💡 Ruby itself can be a major performance bottleneck, even with fast SQL queries, due to issues like serialization and object allocation

🚀 Speed up your API by fixing Ruby performance bottlenecks, not just SQL queries!
