So i dig into some information about optimalizing your game in unity.
If anybody is interested here are some usefull links that can help you build more performant games:
-
Best practices
- This is MUST READ site if you really wanna write good code
-
Optimalization talk on GDC
- More info of that type you can find by googling “Ian Dundore unity”
- Scriptable objects opttimalization
- Scriptable objects example
- Job systems and ECS
Note that some of speaches from GDC are out of date (in newer versions of Unity some of descibed problems are already autoamtically solved)
Hope this will be helpfull for someone 
Ps. If you know any other sited/blogs that might be usefull to learn optimalization guidelines please shere it here
