What are the drawbacks of lock-free queues?

Lock-free queues can lead to complexity in implementation, increased CPU usage, and potential memory management issues.

Can you explain why they might lead to increased CPU usage?

Sure! Lock-free algorithms often require busy-waiting or spinning, which can consume more CPU cycles compared to traditional locking.

What about memory management issues?

Lock-free queues may cause memory leaks or fragmentation if not managed properly, as they often rely on complex memory reclamation techniques.

Are there any scenarios where lock-free queues are preferred despite these drawbacks?

Yes, in high-performance applications where low latency is critical, the benefits of lock-free queues can outweigh their drawbacks.
