hello everyone
I have an issue that's going on around my head these days, I'd like to know how llblgen pro deals with performance issues, for example when having an entity wich has various child collections, and these ones have also their own children
There's a nice explanation at LLBLGenPro Help - Using generated code - Adapter - Prefetch paths - Using prefetch paths, the basics - Optimizing prefetch paths.

how does the internal logic retrieves this information when is accessed? or when you call an entity-property does it exist any database call?.
This depends upon the template set you are using (Adapter or Selfservicing). From your previous posts I assume you are using Adapter.
Adapter don't hit a query when you reference a property, Selfservicing do. However there's various ways to tunning that if you want.
For information about the difference and the work behind template sets, please read:
LLBLGenPro Help - Concepts - Templates and Template Groups - Included template files.

I heard that the mapper does a well done job with data caching to avoid latency times and annecesary db calls, but I'd like to know it from you guys.
Behind the scenes LLBLGenPro do a good work performing DB calls, so is up to developer to write a good code.

any technical article or maybe a self experience?
In my own experience, LLBLGenPro gives me at lest the same performance as if I wouldn't use it. Many things perform even better.
There's a lot of threads discussing the better code approach to certain tasks.
