multithreading or multiprocessing

Question

I am designing a dedicated syslog-processing daemon for Linux that needs to be robust and scalable and I\'m debating multithread vs. multiprocess.

The obvious objection

Answer 1

Thanks everyone for your feedback.

I have decided on a multi-process architecture, similar to the Apache web server. The processes will scale nicely on multi-processor/core systems. Communications will be performed with pipes or sockets.

Processes will be ready to use in a process-pool so there's no process spawning cost.

The performance hit will be negligible in comparison to the robustness I'll gain.
