As my past habits was to always create a thread when something requires more processing time. I'm a bit confused to when to use thread with libev and how to manage longer tasks. My first thought is that I have started to use libev to remove the overhead of thread, context switching and mutex.
I'm trying to come up with some personal rules and I still have some questions that are not answered:
1- How long could I stay in a callback (ex: io watcher callback) and process data until the rest of my system become non responsive (ex: server)?
2- Will it be preferable to simply start a thread if we know that the processing could go higher to a certain threshold?
3- How to determine that acceptable threshold?
Do you have some thought on that subject?
