How do goroutines affect performance in Go?

Goroutines are lightweight threads managed by the Go runtime, allowing concurrent execution. They can improve performance by utilizing CPU resources more efficiently.

Can you explain how they differ from traditional threads?

Unlike traditional threads, goroutines are much lighter and have a smaller memory footprint. The Go scheduler manages them, allowing thousands to run concurrently without the overhead of OS threads.

What are some best practices for using goroutines?

Best practices include limiting the number of goroutines, using channels for communication, and ensuring proper synchronization to avoid race conditions.

Are there any performance drawbacks to using goroutines?

Yes, excessive goroutines can lead to increased context switching and memory usage. It's important to balance concurrency with resource management.
