Introduction to Gosched

runtime.Gosched hints the scheduler to pause the current goroutine and give other goroutines a chance to run.

Usage of Gosched

runtime.Gosched()

Examples and tests

See package

Use Cases

• Improving concurrency in CPU-bound programs.
• Preventing long-running goroutines from starving others.

Common Pitfalls

• Overuse can lead to performance degradation.
• Not a substitute for proper goroutine synchronisation.

Best Practices

• Use sparingly and understand the implications on your program's concurrency.
