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

You've left out too many details. Actually, in terms of what you have already stated, the choice is irrelevant and there is nothing inherently more buggy about multithreading than multiprocessing; you're missing why these techniques have such a reputation. If you aren't sharing data then there isn't much problem to be had (of course, there may be some other issues, but we need details to decide about those). Also, it matters what platform, on UNIX like operating systems, processes are pretty lightweight anyway.

However, there are other issues to consider? What kind of system(s) will you be running on? You definitely don't want to spawn out several processes on a uniprocessor system as you aren't going to get much benefit, depending on some other details you could specify. If you describe the nature of the problem you are trying to solve, we can help further.
