Process vs Threads

Question

How to decide whether to use threads or create separate process altogether in your application to achieve parallelism.

Answer 1

Processes have more isolated memory. This is important for a number of reasons:

• It is harder for a single task to crash the other tasks.
• More memory will be available per process. This is important for large, high-performance applications like Apache or database servers, like Postgres. This is important for both allocated memory and memory mapped files.
