Hi, I have a question about the side effects of setting up bigger limit to the number of the processes, I didn’t find any documentation how it could have impacted the system or to the app that is running on the system, is there maybe more to it? Do you also need to setup some bigger limits for atoms or binary flags for that system?
Depends on your needs. Remember also that there are hard limits. There also is a pull request to increase the default process limit.
The main side effect is that VM will then use more memory by default.
How much more? Is there any documentation on this?
No idea, as I learned it empirically.
2 words per process IIRC.
It may be buried somewhere here: Erlang -- Process and Port Tables
It is an internal implementation detail and can thus change at any time.
