How are signals in Creatio implemented?

I am asking this because, I have an use case where a single data model requires to have triggers setup for multiple business processes. Is there any best practice regarding this like making a main process that will have all the triggers and run sub processes (multiple) based on what field is changed/added?
My current solution will be having all the process as having there own signals but I am afraid if this will slow down my creatio instance.

Thanks.
