7 tips to optimize back-end written in Go

1. Use the latest version of Go 🔗

Make sure you are using the latest version of Go to take advantage of all the performance improvements and bug fixes.

2. Use Goroutines 🔗

Goroutines are lightweight threads that can be used to run multiple tasks concurrently, which can significantly improve performance.

3. Use Profiling Tools 🔗

Profiling tools such as pprof can help you identify bottlenecks in your code and optimize them accordingly.

4. Use Interfaces 🔗

Interfaces allow you to write code that is more flexible and easier to maintain, while also improving performance by avoiding unnecessary type conversions.

5. Avoid Unnecessary Allocations 🔗

Allocations can be expensive, so try to avoid them whenever possible by reusing existing objects or using data structures that don’t require allocations (e.g., slices).

6. Use Caching 🔗

Caching can help reduce latency and improve performance by avoiding unnecessary calculations or database queries for frequently requested data.

7. Optimize Database Queries 🔗

Make sure your database queries are optimized for speed and efficiency by using indexes, caching, and other techniques as needed.
