How can I improve the performance of my Go application using defer?

Using 'defer' in Go can simplify your code, but it may introduce performance overhead. It's best used for cleanup tasks.

What are the performance implications of using defer?

Each deferred function call adds to the stack, which can lead to increased memory usage and slower execution if overused.

Are there alternatives to defer that I should consider?

Yes, you can use explicit function calls for cleanup instead of defer, especially in performance-critical sections.

Can you give me an example of when to avoid using defer?

Avoid using defer in tight loops or performance-sensitive code where every millisecond counts, as it can slow down execution.
