What are the performance differences between threads and processes?

What are the performance differences between threads and processes?

Threads are lighter and share memory, making them faster for communication, while processes are heavier and more isolated.

Can you explain why threads are generally faster?

Threads have lower overhead since they share the same memory space, reducing the time needed for context switching.

Are there any scenarios where processes are better than threads?

Yes, processes are better for tasks that require isolation and stability, like running different applications.

How does this affect multi-core processors?

Multi-core processors can run multiple threads or processes simultaneously, improving performance for both, but threads often utilize cores more efficiently.
